Subject: Re: [PATCH v2 1/3] firmware_loader: make RUST_FW_LOADER_ABSTRACTIONS

Hi Alexandre,
kernel test robot noticed the following build errors:
[auto build test ERROR on 6553a8f168fb7941ae73d39eccac64f3a2b9b399]

patch subject: [PATCH v2 1/3] firmware_loader: make RUST_FW_LOADER_ABSTRACTIONS select FW_LOADER
config: x86_64-kexec (attached as .config)
compiler: clang version 20.1.8 (https://github.com/llvm/llvm-project 87f0227cb60147a26a1eeb4fb06e3b505e9c7261)

the same patch/commit), kindly add following tags

4 config FW_LOADER
5 tristate "Firmware loading facility" if EXPERT
6 select CRYPTO_LIB_SHA256 if FW_LOADER_DEBUG
7 default y
8 help
9 This enables the firmware loading facility in the kernel. The kernel
10 will first look for built-in firmware, if it has any. Next, it will
11 look for the requested firmware in a series of filesystem paths:
12
13 o firmware_class path module parameter or kernel boot param
14 o /lib/firmware/updates/UTS_RELEASE
15 o /lib/firmware/updates
16 o /lib/firmware/UTS_RELEASE
17 o /lib/firmware
18
19 Enabling this feature only increases your kernel image by about
20 828 bytes, enable this option unless you are certain you don't
21 need firmware.
22
23 You typically want this built-in (=y) but you can also enable this
24 as a module, in which case the firmware_class module will be built.
25 You also want to be sure to enable this built-in if you are going to
26 enable built-in firmware (CONFIG_EXTRA_FIRMWARE).

34 Select this option to use dynamic debug to log firmware filenames and
35 SHA256 checksums to the kernel log for each firmware file that is
36 loaded.

43 This enables the Rust abstractions for the firmware loader API.
