From: "Sicelo A. Mhlongo" <absicsz@gmail.com> stable inclusion from stable-v5.10.94 commit 852d7d436fd19be043b33fd31133fb159b91a03b bugzilla: https://gitee.com/openeuler/kernel/issues/I531X9 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit e9af026a3b24f59d7af4609f73e0ef60a4d6d516 ] Since the LED multicolor framework support was added in commit 92a81562e695 ("leds: lp55xx: Add multicolor framework support to lp55xx") LEDs on this platform stopped working. Fixes: 92a81562e695 ("leds: lp55xx: Add multicolor framework support to lp55xx") Fixes: ac219bf3c9bd ("leds: lp55xx: Convert to use GPIO descriptors") Signed-off-by: Merlijn Wajer <merlijn@wizzup.org> Signed-off-by: Sicelo A.
