Bluetooth: btrtl: Prevent potential NULL dereference

CVE-2025-37792

Description

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

Bluetooth: btrtl: Prevent potential NULL dereference

The btrtl_initialize() function checks that rtl_load_file() either had an error or it loaded a zero length file. However, if it loaded a zero length file then the error code is not set correctly. It results in an error pointer vs NULL bug, followed by a NULL pointer dereference. This was detected by Smatch:

drivers/bluetooth/btrtl.c:592 btrtl_initialize() warn: passing zero to 'ERR_PTR'
