Dear Hans de Goede, I have Ubuntu (raring) and recently bought digital
microscope eyepiece Lomo MD300. It is the same device as Future Optics MVV3000.
Unfortunately it does not work out of box. Moreover drivers refused to work
under Windows 7 as well leaving me only with Win Xp working system. I have had
no choice but to examine what happened in USB bus and attempt to reproduce the
sequence. So, i have download the source(3.8.0-30 kernel) and made required
changes to driver to make my hardware work.
I submit my changed files to you as maintainer of the driver so you can
integrade my changes into main stream. Thanx. Hopefully my Ubuntu will work
with my hardware out of box.

[media] dvb-usb: fix error handling in ttusb_dec_probe()
There is an asymmetry in ttusb_dec_init_usb()-ttusb_init_rc()
and ttusb_dec_exit_usb()-ttusb_dec_exit_rc() in terms of resources
allocated-deallocated. irq_urb and irq_buffer are allocated in
ttusb_dec_init_usb(), while they are deallocated in ttusb_dec_exit_rc().
As a result there is a leak of them in ttusb_dec_probe().
The patch fixes the asymmetry and a leak on a failure path in ttusb_dec_init_usb().
By the way, it
- removes usage of -1 as a custom error code,
- replaces GFP_ATOMIC by GFP_KERNEL in usb_alloc_coherent() in ttusb_dec_init_usb()
as soon as all other memory allocation done with GFP_KERNEL;
- refactors ttusb_dec_boot_dsp() in an equivalent way except for returning 0
instead of 1 if ttusb_dec_boot_dsp() succeed in (!mode) branch.

When the tuner part of the ds3000 driver was split to share code with the m88rs2000 driver, the ts2020 driver used
the frequency divider value from the m88rs2000 driver. However the ds3000 driver requires a different value, and this
resulted in some frequecies being invisible to the tuner. This patch adds back in the value needed for the ds3000 driver
and configured as an option in the dw2102 frontend driver.

First round of IIO fixes for 3.12
A series of wrong 'struct dev' assumptions in suspend/resume callbacks
following on from this issue being identified in a new driver review.
One to watch out for in future.
A number of driver specific fixes
1) at91 - fix a overflow in clock rate computation
2) dummy - Kconfig dependency issue
3) isl29018 - uninitialized value
4) hmc5843 - measurement conversion bug introduced by recent cleanup.
5)
ade7854-spi - wrong return value.
Some IIO core fixes
1) Wrong value picked up for event code creation for a modified channel
2) A null dereference on failure to initialize a buffer after no buffer has
been in use, when using the available_scan_masks approach.
3) Sampling not stopped when a device is removed. Effects forced removal
such as hot unplugging.
4) Prevent device going away if a chrdev is still open in userspace.
5) Prevent race on chardev opening and device being freed.
6) Add a missing iio_buffer_init in the call back buffer.
These last few are the first part of a set from Lars-Peter Clausen who
has been taking a closer look at our removal paths and buffer handling
than anyone has for quite some time.

Btrfs: dir_inode_operations should use btrfs_update_time also
Commit
2bc5565286121d2a77ccd728eb3484dff2035b58 (Btrfs: don't update atime on
RO subvolumes) ensures that the access time of an inode is not updated when
the inode lives in a read-only subvolume.
However, if a directory on a read-only subvolume is accessed, the atime is
updated. This results in a write operation to a read-only subvolume. I
believe that access times should never be updated on read-only subvolumes.

Btrfs: improve replacing nocow extents
Various people have hit a deadlock when running btrfs/011. This is because when
replacing nocow extents we will take the i_mutex to make sure nobody messes with
the file while we are replacing the extent. The problem is we are already
holding a transaction open, which is a locking inversion, so instead we need to
save these inodes we find and then process them outside of the transaction.
Further we can't just lock the inode and assume we are good to go. We need to
lock the extent range and then read back the extent cache for the inode to make
sure the extent really still points at the physical block we want. If it
doesn't we don't have to copy it. Thanks,

A user reported a bug where his log would not replay because he was getting
-EEXIST back. This was because he had a file moved into a directory that was

processed first when replaying the log, and so we add the inode ref in for the
directory it was moved to. But then we process the directories DIR_INDEX item
and try to add the inode ref for that inode and it fails because we already
added it when we replayed the inode. To solve this problem we need to just

Btrfs: check roots last log commit when checking if an inode has been logged
Liu introduced a local copy of the last log commit for an inode to make sure we
actually log an inode even if a log commit has already taken place. In order to
make sure we didn't relog the same inode multiple times he set this local copy
to the current trans when we log the inode, because usually we log the inode and
then sync the log. The exception to this is during rename, we will relog an
inode if the name changed and it is already in the log. The problem with this
is then we go to sync the inode, and our check to see if the inode has already
been logged is tripped and we don't sync the log. To fix this we need to _also_
check against the roots last log commit, because it could be less than what is
in our local copy of the log commit. This fixes a bug where we rename a file
into a directory and then fsync the directory and then on remount the directory

Btrfs: actually limit the size of delalloc range
So forever we have had this thing to limit the amount of delalloc pages we'll
setup to be written out to 128mb. This is because we have to lock all the pages
in this range, so anything above this gets a bit unweildly, and also without a
limit we'll happily allocate gigantic chunks of disk space. Turns out our check
for this wasn't quite right, we wouldn't actually limit the chunk we wanted to
write out, we'd just stop looking for more space after we went over the limit.
So if you do a giant 20gb dd on my box with lots of ram I could get 2gig
extents. This is fine normally, except when you go to relocate these extents
and we can't find enough space to relocate these moster extents, since we have

Btrfs: allocate the free space by the existed max extent size when ENOSPC
By the current code, if the requested size is very large, and all the extents
in the free space cache are small, we will waste lots of the cpu time to cut
the requested size in half and search the cache again and again until it gets
down to the size the allocator can return. In fact, we can know the max extent
size in the cache after the first search, so we needn't cut the size in half
repeatedly, and just use the max extent size directly. This way can save
lots of cpu time and make the performance grow up when there are only fragments
in the free space cache.
According to my test, if there are only 4KB free space extents in the fs,
and the total size of those extents are 256MB, we can reduce the execute
time of the following test from 5.4s to 1.4s.
dd if=/dev/zero of=<testfile> bs=1MB count=1 oflag=sync
