need to look for clocks on this model so it makes more sense to just

This handles the timeout error codes sent by the chip as part of the
bootloader signatures during firmware download process.
When the bootloader does not receive a response packet from the host
within a specific time, it adds an error code to the bootloader
signature while requesting for the FW chunk from the same offset.
The host is expected to clear this error code with a NAK, and reply to
only those bootloader signatures which have error code 0.
However, the driver was ignoring this error code and replying with the
firmware chunks instead, which is apparently ignored by the chip and the
chip resends the same bootloader signature with the error code again. This
happens in a loop until the error code self clears and firmware download
proceeds ahead, adding a couple of milliseconds to the total firmware
download time.
Commit 689ca16e5232 was an initial implementation which simply printed
the following line during driver debug:
- FW Download received err 0x04 from chip
This commit adds the expected handling to the error codes.
This error handling is valid for data_req bootloader signatures for V3
and future bootloader versions.

This updates the firmware names of 3 chipsets: w8987, w8997, w9098.
These changes are been done to standardize chip specific firmware

For dual-radio WiFi+BT chipsets:
- <protocol-BT><chip-name>_bt_v<HW-version>.bin
For tri-radio WiFi+BT+15.4 chipsets:
- <protocol-BT><protocol-15.4><chip-name>_bt_v<HW-version>.bin
To maintain backward compatibility, this commit adds a provision to
request older firmware file name, if new firmware file name not found in
/lib/firmware/nxp/.

When HCI raw sockets are opened, the Bluetooth kernel module doesn't
track CIS/BIS connections. User-space applications have to identify
ISO data by maintaining connection information and look up the mapping
for each ACL data packet received. Besides, btsnoop log captured in
kernel couldn't tell ISO data from ACL data in this case.
To avoid additional lookups, this patch introduces vendor-specific
packet classification for Intel BT controllers to distinguish
ISO data packets from ACL data packets.

This is an effort to get rid of all multiplications from allocation
functions in order to prevent integer overflows [1][2].
As the "dl" variable is a pointer to "struct rfcomm_dev_list_req" and
this structure ends in a flexible array:
struct rfcomm_dev_list_req {
[...]
struct rfcomm_dev_info dev_info[];
};
the preferred way in the kernel is to use the struct_size() helper to
do the arithmetic instead of the calculation "size + count * size" in
the kzalloc() and copy_to_user() functions.
At the same time, prepare for the coming implementation by GCC and Clang
of the __counted_by attribute. Flexible array members annotated with
__counted_by can have their accesses bounds-checked at run-time via
CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for
strcpy/memcpy-family functions).
In this case, it is important to note that the logic needs a little
refactoring to ensure that the "dev_num" member is initialized before
the first access to the flex array. Specifically, add the assignment
before the list_for_each_entry() loop.
Also remove the "size" variable as it is no longer needed.
This way, the code is more readable and safer.
This code was detected with the help of Coccinelle, and audited and
modified manually.
