linux-next: build failure after merge of the drm-misc tree

Hi all,

After merging the drm-misc tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/video/fbdev/controlfb.c: In function 'controlfb_mmap':
drivers/video/fbdev/controlfb.c:756:23: error: implicit declaration of function 'pgprot_cached_wthru'; did you mean 'pgprot_cached'? [-Werror=implicit-function-declaration]
756 | vma->vm_page_prot = pgprot_cached_wthru(vma->vm_page_prot);
| ^~~~~~~~~~~~~~~~~~~
| pgprot_cached
drivers/video/fbdev/controlfb.c:756:23: error: incompatible types when assigning to type 'pgprot_t' {aka 'struct <anonymous>'} from type 'int'

Presumably exposed by commit

a07a63b0e24d ("video: fbdev: controlfb: add COMPILE_TEST support")

I just turned off COMPILE_TEST again for today. Please let me know when
this is fixed.
