staging: fsl-mc: don't use object versions to make binding decisions
Up until now if the object version expected by a driver (in the API header
file) did not match the actual object version in the MC hardware the bus
driver refused to bind the object to the driver or printed out WARN_ON
dumps.
This patch removes those checks, and the responsibility of object version
checking should now be done in the object drivers themselves. If the actual
version discovered is not supported, the driver's probe function should fail.
Drivers should use version checks to support new features and provide
backwards compatibility if at all possible.
This patch also removes the checks that caused bus driver probing to fail
if the overall MC version discovered did not match the firmware version
from the API header...this was too strict. The overall MC version is
informational like a release number, and continues to be printed in the
boot log.

staging/android: refactor SYNC IOCTLs
Change SYNC_IOC_FILE_INFO (former SYNC_IOC_FENCE_INFO) behaviour to avoid
future API breaks and optimize buffer allocation.
Now num_fences can be filled by the caller to inform how many fences it
wants to retrieve from the kernel. If the num_fences passed is greater
than zero info->sync_fence_info should point to a buffer with enough space
to fit all fences.
However if num_fences passed to the kernel is 0, the kernel will reply
with number of fences of the sync_file.
Sending first an ioctl with num_fences = 0 can optimize buffer allocation,
in a first call with num_fences = 0 userspace will receive the actual
number of fences in the num_fences filed.
Then it can allocate a buffer with the correct size on sync_fence_info and
call SYNC_IOC_FILE_INFO again, but now with the actual value of num_fences
in the sync_file.
info->sync_fence_info was converted to __u64 pointer to prevent 32bit
compatibility issues. And a flags member was added.
An example userspace code for the later would be:
struct sync_file_info *info;
int err, size, num_fences;
info = malloc(sizeof(*info));
info.flags = 0;
err = ioctl(fd, SYNC_IOC_FILE_INFO, info);
num_fences = info->num_fences;
if (num_fences) {
info.flags = 0;
size = sizeof(struct sync_fence_info) * num_fences;
info->num_fences = num_fences;
info->sync_fence_info = (uint64_t) calloc(num_fences,
sizeof(struct sync_fence_info));
err = ioctl(fd, SYNC_IOC_FILE_INFO, info);
}
Finally the IOCTLs numbers were changed to avoid any potential old
userspace running the old API to get weird errors. Changing the opcodes
will make them fail right away. This is just a precaution, there no
upstream users of these interfaces yet and the only user is Android, but
we don't expect anyone trying to run android userspace and all it
dependencies on top of upstream kernels.
