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.
