From: Sam Ravnborg <sam@xxxxxxxxxxxx> [ Upstream commit 99bd9a4f87926e12ce60796d7db1d6b226aca5e3 ] sparc32 do not support generic isa dma, so do not select the symbol. This fixes the following warnings: dma.c:70:5: error: no previous prototype for 'request_dma' [-Werror=missing-prototypes] dma.c:88:6: error: no previous prototype for 'free_dma' [-Werror=missing-prototypes] Signed-off-by: Sam Ravnborg <sam@xxxxxxxxxxxx> Fixes: 0fcb70851fbf ("Makefile.extrawarn: turn on missing-prototypes globally") Acked-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Tested-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> # build-tested Cc: Andreas Larsson <andreas@xxxxxxxxxxx> Cc: "David S.
