net: wireless : bcmdhd fix the type of bssidx of P2P

Currently we set WL_INVALID(-1) to bssidx for deinit.
However, the bssdix has u32 type.
so, we need to change type to s32.

ext4: Add support for FIDTRIM, a best-effort ioctl for deep discard trim

* What
This provides an interface for issuing an FITRIM which uses the
secure discard instead of just a discard.
Only the eMMC command is "secure", and not how the FS uses it:
due to the fact that the FS might reassign a region somewhere else,
the original deleted data will not be affected by the "trim" which only
handles un-used regions.
So we'll just call it "deep discard", and note that this is a
"best effort" cleanup.

* Why
Once in a while, We want to be able to cleanup most of the unused blocks
after erasing a bunch of files.
We don't want to constantly secure-discard via a mount option.

From an eMMC spec perspective, it tells the device to really get rid of
all the data for the specified blocks and not just put them back into the
pool of free ones (unlike the normal TRIM). The eMMC spec says the
secure trim handling must make sure the data (and metadata) is not available
anymore. A simple TRIM doesn't clear the data, it just puts blocks in the
free pool.
JEDEC Standard No. 84-A441
  7.6.9 Secure Erase
  7.6.10 Secure Trim

From an FS perspective, it is acceptable to leave some data behind.
 - directory entries related to deleted files
 - databases entries related to deleted files
 - small-file data stored in inode extents
 - blocks held by the FS waiting to be re-used (mitigated by sync).
 - blocks reassigned by the FS prior to FIDTRIM.

usb: gadget: f_audio_source: Fixed USB Audio Class Interface Descriptor

Fixed Android Issue #56549.

When both Vendor Class and Audio Class are activated for AOA 2.0,
the baInterfaceNr of the AudioControl Interface Descriptor points
to wrong interface numbers. They should be pointing to
Audio Control Device and Audio Streaming interfaces.

Replaced baInterfaceNr with the correct value.
