fbdev: Replace fb_pgprotect() with pgprot_framebuffer()
Rename the fbdev mmap helper fb_pgprotect() to pgprot_framebuffer(). The helper sets VMA page-access flags for framebuffers in device I/O memory. Also clean up the helper's parameters and return value. Instead of the VMA instance, pass the individial parameters separately: existing page-access flags, the VMAs start and end addresses and the offset in the underlying device memory rsp file. Return the new page-access flags. These changes align pgprot_framebuffer() with other pgprot_() functions. v4: * fix commit message (Christophe) v3: * rename fb_pgprotect() to pgprot_framebuffer() (Arnd) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org> # m68k Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230922080636.26762-3-tzimmermann@suse.de
