Summary
Bluetooth: hci_ll: Fix firmware leak on error path
Details

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_ll: Fix firmware leak on error path

Smatch reports:

drivers/bluetooth/hcill.c:587 downloadfirmware() warn: 'fw' from request_firmware() not released on lines: 544.

In downloadfirmware(), if requestfirmware() succeeds but the returned firmware content is invalid (no data or zero size), the function returns without releasing the firmware, resulting in a resource leak.

Fix this by calling releasefirmware() before returning when requestfirmware() succeeded but the firmware content is invalid.
