Re: [PATCH net v2] net: airoha: npu: load the firmware without the sysfs fallback

Hello:

This patch was applied to netdev/net-next.git (main)

airoha_npu_load_firmware() maps a missing firmware file to -EPROBE_DEFER
so that the NPU can be brought up once the rootfs carrying /lib/firmware
has been mounted. That mapping holds only as long as request_firmware()
reports -ENOENT.

It does not when the sysfs fallback is in play. With
CONFIG_FW_LOADER_USER_HELPER_FALLBACK set, or with the fallback armed at
runtime through /proc/sys/kernel/firmware_config/force_sysfs_fallback,
request_firmware() hands the request to a userspace helper, waits out the
full loading_timeout and returns -ETIMEDOUT. The -ENOENT test no longer
matches, dev_err_probe() turns the result into a hard failure, and the
NPU is left unbound after stalling the boot for 60 seconds:
