From: simran singhal Date: Sun, 12 Mar 2017 16:55:42 +0000 (+0530) Subject: staging: comedi: amplc_pci224: Convert macro GAT_CONFIG to static inline function X-Git-Tag: v4.12-rc1~84^2~560 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cb52fce16027d79a97d0870a1110d4a4493fa0a8;p=karo-tx-linux.git staging: comedi: amplc_pci224: Convert macro GAT_CONFIG to static inline function Convert macro GAT_CONFIG to static inline function as static inline functions are preferred over macros. This change is possible since the arguments at all call sites have the same type. The uses were updated with Coccinelle: @r1@ expression dev,reg,chan,src; @@ -GAT_CONFIG(chan, src) +pci224_gat_config(chan, src) Also, the comment describing the macro has been removed.
