When we run the following commands in turn (with
CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0),
speaker-test -Dhw:0,3 -c2 -twav # HDMI
speaker-test -Dhw:0,0 -c2 -twav # Analog
The second command will produce sound in the analog lineout _as well as_
HDMI sink. The root cause is, device 0 "reuses" the same stream tag that
was used by device 3, and the "intelhdmi - sticky stream id" patch leaves
the HDMI codec in a functional state. So the HDMI codec happily accepts
the audio samples which reuse its stream tag.
The proposed solution is to remember the last device each azx_dev was
assigned to, and prefer to
1) reuse the azx_dev (and hence the stream tag) the HDMI codec last used
2) or assign a never-used azx_dev for HDMI
With this patch and the above two speaker-test commands,
HDMI codec will use stream tag 8 and Analog codec will use 5.
The stream tag used by HDMI codec won't be reused by others, as long
as we don't run out of the 4 playback azx_dev's. The legacy Analog
codec will continue to use stream tag 5 because its device id is 0
(this is a bit tricky).

BIOS information is now checked whether it begins with the strings stored
in the BIOS table. Previous method did a strcmp, what lead to problems if
BIOS information has appended whitespaces.

The module alias currently matches any Acer computer but when loaded the

ACPI: do not select ACPI_DOCK from ATA_ACPI
In March 2008 commit
0ac4a3c2fbbcadc3e96e4dc47d4ae802d66e6f67 ("ACPI: fix
ATA_ACPI build") made CONFIG_ACPI_DOCK be selected by CONFIG_ATA_ACPI because
of a build error when CONFIG_ATA_ACPI=y and CONFIG_ACPI_DOCK=m.
However, in September 2008 commit

("dock: make dock driver not a module") removed the possibility of having
CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when
CONFIG_ATA_ACPI=y.
This makes the kernel ~5 Kb smaller for people who don't have a dock by
allowing them to not have ACPI_DOCK compiled-in because of ATA_ACPI=y.

i2c-omap: OMAP3: Fix I2C lockup during timeout/error cases
Current OMAP3 I2C driver code does not follow the correct sequence for soft
reset. Due to this, lock up issues are reported during timeout/error cases.
This patch fixes above issue by disabling I2C controller as per OMAP3430 TRM
for soft reset. As per TRM, I2C controller needs to be disabled as a first
step during soft reset.
Here is correct soft reset sequence:
a. Ensure that the module is disabled
(clear the I2Ci.I2C_CON[15] I2C_EN bit to 0).
b. Set the I2Ci.I2C_SYSC[1] SRST bit to 1.
c. Enable the module by setting I2Ci.I2C_CON[15] I2C_EN bit to 1.
d. Check the I2Ci.I2C_SYSS[0] RDONE bit until it is set to 1 to
indicate the software reset is complete.

Commit
ef871432... (i2c-omap: OMAP3: PM: (re)init for every transfer

contents be written to the OMAP_I2C_IE_REG every time omap_i2c_unidle

to zero.
In omap_i2c_probe, omap_i2c_unidle() is called prior to omap_i2c_init(),
in which case dev->iestate has not yet been initialized and will be set
to zero. Having this value written to the registers causes deadlock

This reverts commit
9f15226e75583547aaf542c6be4bdac1060dd425. It's just
wrong, and broke resume for Rafael even on a non-AMD CPU.
As Rafael says:
"... it causes microcode_init_cpu() to be called during resume even for
CPUs for which there's no microcode to apply. That, in turn, results
in executing request_firmware() (on Intel CPUs at least) which doesn't
work at this stage of resume (we have device interrupts disabled, I/O
devices are still suspended and so on).
If I'm not mistaken, the "if (uci->valid)" logic means "if that CPU is
known to us" , so before commit
9f15226e755 microcode_resume_cpu() was
called for all CPUs already in the system during suspend, which was
the right thing to do. The commit changed it so that the CPUs without
microcode to apply are now treated as "unknown", which is not quite
right.
The problem this commit attempted to solve has to be handled
differently."

SYSCTL: Print binary sysctl warnings (nearly) only once
When printing legacy sysctls print the warning message
for each of them only once. This way there is a guarantee
the syslog won't be flooded for any sane program.
The original attempt at this made the tables non const and stored
the flag inline.
Linus suggested using a separate hash table for this, this is based on a
code snippet from him.
The hash implies this is not exact and can sometimes not print a
new sysctl due to a hash collision, but in practice this should not
be a problem
I used a FNV32 hash over the binary string with a 32byte bitmap. This
gives relatively little collisions when all the predefined binary sysctls
are hashed:
size 256
bucket
length number
0: [25]
1: [67]

3: [47]

USB: musb: gadget_ep0: avoid SetupEnd interrupt
Gadget stalling a zero-length SETUP request results in this error message:
SetupEnd came in a wrong ep0stage idle
In order to avoid it, always set the CSR0.DataEnd bit after detecting a zero-
length request. Add the missing '\n' to the error message itself as well...

USB: musb: fix for crash in DM646x USB when (CPPI)DMA is enabled
Race condition exists between the cppi_interrupt handler and
davinci_interrupt handler w.r.t completing a TX IO. Since DM646x
has seperate DMA and USB endpoint interrupts cppi_interrupt handler
needs to hold the lock while operating on the endpoint.
Update over previous patch to avoid taking the lock if already
taken. Tested on DM644x, DM355 and DM646x platforms.

USB: musb: do not work if no gadget driver is loaded
On OTG and gadget-only configurations, we need a gadget driver
in order to work properly, so avoid changing operation modes
when there's no gadget driver loaded.

USB: musb: gadget: set otg tranceiver to idle when registering gadget
When registering gadget driver, the state of the transceiver
must be set from undefined (no gadget) to b_idle.
Module unload sets the transceiver state to undefined state.
After the first load/unload pair, the reset irq will be lost.
