Looking at the macro in asm-generic/fb.h, fb_pgprotect() is being replaced with
a no-op function. Is that intentional? Can you briefly explain the background
for this change?
Patch 01 of this patchset changes the generic fb_pgprotect() to set pgprot_writecombine(). So on SH, there should be no change at all.
Best regards
Thomas
