[PATCH 01/10] platform/x86: fujitsu-laptop: clearly denote backlight-related symbols

From: MichaÅ KÄpieÅ
Date: Wed Feb 08 2017 - 09:22:41 EST

From: Alan Jenkins <alan-jenkins@xxxxxxxxxxxxxx>

Unify naming for all backlight-related functions, structures, variables
and constants by using a consistent "_bl"/"_BL" suffix/infix. Adjust
indentation to make checkpatch happy.
