From f22bbf122a4509c1192412c16e2caf3fa454723d Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Sun, 25 Nov 2012 16:23:03 +0000 Subject: [PATCH] AA: generic: ar8216: introduce ar8216_mib_op helper Backport of r34297. The ar8216_mib_{capture,flush} functions are similar. Move the common code into a helper and use that from the original functions. This change also fixes a lockdep warning in ar8216_mib_flush.
