# Firmware loaded by Android from vendor partition at runtime, not embedded.
# Android's ueventd serves firmware from its firmware_directories (which include
# /vendor/firmware) via the kernel's sysfs userspace-helper fallback. This is
# required because the kernel's built-in fw_path[] only covers /lib/firmware*
# (absent on Android) and because built-in drivers (e.g. brcmfmac) request
# firmware before /vendor is mounted -- the fallback's blocking wait bridges
# that gap. Do NOT embed firmware (EXTRA_FIRMWARE) on Android.
