Subject[PATCH 5.10 199/599] video: fbdev: controlfb: Fix COMPILE_TEST build
Date
From: YueHaibing <yuehaibing@huawei.com>

[ Upstream commit 567e44fb51b4f909ae58038a7301352eecea8426 ]

If PPC_BOOK3S, PPC_PMAC and PPC32 is n, COMPILE_TEST build fails:

drivers/video/fbdev/controlfb.c:70:0: error: "pgprot_cached_wthru" redefined [-Werror]
#define pgprot_cached_wthru(prot) (prot)

In file included from ./arch/powerpc/include/asm/pgtable.h:20:0,
from ./include/linux/pgtable.h:6,
from ./include/linux/mm.h:33,
from drivers/video/fbdev/controlfb.c:37:

#define pgprot_cached_wthru(prot) (__pgprot((pgprot_val(prot) & ~_PAGE_CACHE_CTL) | \
