From: Mauro Carvalho Chehab Date: Sun, 7 Apr 2013 23:52:16 +0000 (-0300) Subject: [media] mb86a20s: Use 'layer' instead of 'i' on all places X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5cb88ca84aa8dc4efcabd8482fff6002774c7f03;p=linux-beck.git [media] mb86a20s: Use 'layer' instead of 'i' on all places We're using the anonymous 'i' to indicate the layer number on several places on the driver. That's not good, as some cut-and-paste type of change might be doing the wrong thing. So, call it as "layer" everywhere.
