Subject: [PATCH 6.8 532/715] sparc32: Do not select GENERIC_ISA_DMA

From: Sam Ravnborg <sam@...nborg.org>

[ 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@...nborg.org>
Fixes: 0fcb70851fbf ("Makefile.extrawarn: turn on missing-prototypes globally")
Acked-by: Randy Dunlap <rdunlap@...radead.org>
