The patch titled Subject: backlight: ams369fg06: remove unnecessary NULL deference check has been removed from the -mm tree. Its filename was backlight-ams369fg06-remove-unnecessary-null-deference-check.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Jingoo Han <jg1.han@xxxxxxxxxxx> Subject: backlight: ams369fg06: remove unnecessary NULL deference check Remove unnecessary NULL deference check, because it was already checked in ams369fg06_probe(). Also, unnecessary parentheses are removed in ams369fg06_power_is_on().
