From 3f1b8739a498c7570ca2fae6c49fd1561ef2358c Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Sat, 17 Aug 2013 14:09:32 +0200 Subject: [PATCH] rt2x00: rt2800lib: move rt2800_adjust_freq_offset function Move the rt2800_adjust_freq_offset function before the channel configuration functions to make it usable from those without a forward declaration. The patch contains no functional changes. Signed-off-by: Gabor Juhos Signed-off-by: John W.
