If anyone has any objections, please let me know. ------------------ From: Takashi Iwai commit 2338f73d407d5abe2036d92716ba25ef5279c3d2 upstream. The commit [b67893206fc0: leds:lp55xx: fix firmware loading error] tries to address the firmware file handling with user helper, but it sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK. Since the wrong option was enabled, the system got a regression -- it suffers from the unexpected long delays for non-present firmware files. This patch corrects the Kconfig dependency to the right one, CONFIG_FW_LOADER_USER_HELPER. This doesn't change the fallback behavior but only enables UMH when needed.
