From 052ddf7b86d2d9443bce77ef5b5b1ef61a3b79fc Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Fri, 22 Sep 2023 10:04:56 +0200 Subject: 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 Reviewed-by: Arnd Bergmann Acked-by: Geert Uytterhoeven # m68k Reviewed-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20230922080636.26762-3-tzimmermann@suse.de --- arch/sparc/include/asm/fb.h | 15 +++++++++------ 1 file changed, 9 insertions(+), 6 deletions(-) (limited to 'arch/sparc') diff --git a/arch/sparc/include/asm/fb.h b/arch/sparc/include/asm/fb.h index 572ecd3e1cc4..24440c0fda49 100644 --- a/arch/sparc/include/asm/fb.h +++ b/arch/sparc/include/asm/fb.h @@ -4,15 +4,18 @@ #include +#include + struct fb_info; -struct file; -struct vm_area_struct; #ifdef CONFIG_SPARC32 -static inline void fb_pgprotect(struct file *file, struct vm_area_struct *vma, - unsigned long off) -{ } -#define fb_pgprotect fb_pgprotect +static inline pgprot_t pgprot_framebuffer(pgprot_t prot, + unsigned long vm_start, unsigned long vm_end, + unsigned long offset) +{ + return prot; +} +#define pgprot_framebuffer pgprot_framebuffer #endif int fb_is_primary_device(struct fb_info *info); -- cgit v1.2.3
