CONFIG_SSB_DEBUG is used in one header file and nowhere else, so remove it and the now-empty inline function that contained it. Also remove the call to the empty inline function. The empty "default:" case is kept to prevent 2 compiler warnings: drivers/ssb/main.c:1133:9: warning: enumeration value 'SSB_BUSTYPE_PCMCIA' not handled in switch [-Wswitch] drivers/ssb/main.c:1133:9: warning: enumeration value 'SSB_BUSTYPE_SDIO' not handled in switch [-Wswitch] Reported-by: Ying Sun <sunying@xxxxxxxxxxxxxxxx> Link: https://lore.kernel.org/lkml/4e8525fe.607e2.18a8ddfdce8.Coremail.sunying@xxxxxxxxxxxxxxxx/ Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Cc: Michael Büsch <m@xxxxxxx> Cc: linux-wireless@xxxxxxxxxxxxxxx Cc: Kalle Valo <kvalo@xxxxxxxxxx> --- This Closes only 1 of the 3 issues reported in the Link. drivers/ssb/main.c | 1 - include/linux/ssb/ssb.h | 8 -------- 2 files changed, 9 deletions(-) diff -- a/include/linux/ssb/ssb.h b/include/linux/ssb/ssb.h --- a/include/linux/ssb/ssb.h +++ b/include/linux/ssb/ssb.h @@ -621,14 +621,6 @@ extern u32 ssb_dma_translation(struct ss #define SSB_DMA_TRANSLATION_MASK 0xC0000000 #define SSB_DMA_TRANSLATION_SHIFT 30 -static inline void __cold __ssb_dma_not_implemented(struct ssb_device *dev) -{ -#ifdef CONFIG_SSB_DEBUG - printk(KERN_ERR "SSB: BUG!
