The patch titled Subject: backlight: lp855x_bl: simplify bl_get_brightness() has been removed from the -mm tree. Its filename was backlight-lp855x_bl-simplify-bl_get_brightness.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: "Kim, Milo" <Milo.Kim@xxxxxx> Subject: backlight: lp855x_bl: simplify bl_get_brightness() Getting the brightness value is not critical, no need to read the actual register value. To simplify it, just return the 'bl->props.brightness' value. Then, lp855x_read_byte() can be removed, not used any more.
