[PATCH v3 02/19] arch/arc: Implement with generic helpers

Thomas Zimmermann
2023-04-17T12:57:27Z

Replace the architecture's fbdev helpers with the generic ones from
<asm-generic/fb.h>. On arc, pgprot_writecombine() and pgprot_noncached()
are the same; hence no functional changes.

v3:
* use default implementation for fb_pgprotect() (Arnd)
