wavelan_cs: stop inlining largish static functions
Hi John, Can you please take a look at this patch? drivers/net/wireless/wavelan_cs.c has unusually large number of static inline functions - 27. I looked through them and 20 of them do not seem to warrant inlining. Some are really big; others call mdelay(1) or busy-wait for a bit to be set in a hardware register - it's pointless to optimize such functions for speed. This patch removes "inline" from these static function (regardless of number of callsites - gcc nowadays auto-inlines statics with one callsite).
