Subject: leds:lp55xx: Correct Kconfig dependency for f/w user helper
From: Takashi Iwai <tiwai@xxxxxxx>
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.
