At certain point in diag driver there can be integer underflow and thus can lead to memory leak. Bound checks are placed to ensure correct behavior of condition statements. Change-Id: I47e02f764c2c7412db6f90fd42192fee32a761d3 CRs-fixed: 549470 Signed-off-by: Katish Paran <kparan@codeaurora.org>

Dirty widget list can be accessed by multiple paths in dapm framework. Dirty list is protected by dapm mutex. Since stream_event function accesses the dirty list, it should acquire dapm mutex instead of codec mutex.

This reverts commit Ia8e82a6ad327acddc135835268a755e3646d2ee8. Calling hrtimer_forward_now() outside of the hrtimer callback context and not restarting it seems to be a misuse of the hrt APIs. Change-Id: Idd3f967d8037435ec43bbd843ce122d989aa838a Signed-off-by: Srinu Gorle <sgorle@codeaurora.org>
Variable size inside buspm_xfer_req can be negative and thus would be a large positive number resulting in arbitary Kernel read. This patch corrects this value. CRs-Fixed: 563529 Change-Id: I877db6960530d6c7d1486da9cfdc15a43e57e152 Signed-off-by: Sana Venkat Raju <c_vsana@codeaurora.org>

When device power up, probe happens where camera sensors connected in each slot are detected by reading its chip id. Add retry mechanism to try 3 times to read chip id for detecting camera sensors.

This makes it possible to let gdb access mappings of the process that is being debugged. uio_mmap_logical was moved and uio_vm_ops renamed to group related code and differentiate to new stuff.

Nico Golde reports a few straggling uses of [io_]remap_pfn_range() that really should use the vm_iomap_memory() helper. This trivially converts two of them to the helper, and comments about why the third one really needs to continue to use remap_pfn_range(), and adds the missing size check.
