From: Bob Copeland Date: Tue, 31 Mar 2009 02:30:30 +0000 (-0400) Subject: ath: move more setup code into ath_regd_init X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e3bb249be89dd387e78ca382d08fad31745edac9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ath: move more setup code into ath_regd_init Setup the wiphy regulatory parameters when first initializing the Atheros regulatory module. We can remove five exported symbols this way and simplify the driver code for both ath5k and ath9k. Signed-off-by: Bob Copeland Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
