From fbf8b5d251e8b4e1b01c591be313c63cb9e1526a Mon Sep 17 00:00:00 2001 From: Junjie Cao Date: Tue, 4 Aug 2026 11:02:55 +0800 Subject: [PATCH] backlight: aw99706: Honor the core blank state in update_status() update_status() passes props.brightness straight to the hardware and ignores the power/blank state tracked by the core. Writing 4 to the bl_power sysfs attribute or blanking the framebuffer therefore leaves the backlight lit. Use backlight_get_brightness(), which returns 0 while the device is blanked.
