fbdev: Push pgprot_decrypted() into mmap implementations If a driver sets struct fb_ops.fb_mmap, the fbdev core automatically calls pgprot_decrypted(). But the default fb_mmap code doesn't handle pgprot_decrypted(). Move the call to pgprot_decrypted() into each drivers' fb_mmap function. This only concerns fb_mmap functions for system and DMA memory. For I/O memory, which is the default case, nothing changes. The fb_mmap for I/O-memory can later be moved into a helper as well. DRM's fbdev emulation handles pgprot_decrypted() internally via the Prime helpers. Fbdev doesn't have to do anything in this case. In cases where DRM uses deferred I/O, this patch updates fb_mmap correctly.

fbdev/sa1100fb: Initialize fb_ops to fbdev I/O-memory helpers Initialize the instance of struct fb_ops with fbdev initializer macros for framebuffers in I/O address space. Set the read/write, draw and mmap callbacks to the correct implementation and avoid implicit defaults. Also select the necessary I/O helpers in Kconfig. Fbdev drivers sometimes rely on the callbacks being NULL for a default implementation to be invoked; hence requiring the I/O helpers to be built in any case. Setting all callbacks in all drivers explicitly will allow to make the I/O helpers optional. This benefits systems that do not use these functions. No functional changes.

video: constify fb ops across all drivers Now that the fbops member of struct fb_info is const, we can start making the ops const as well. This does not cover all drivers; some actually modify the fbops struct, for example to adjust for different configurations, and others do more involved things that I'd rather not touch in practically obsolete drivers. Mostly this is the low hanging fruit where we can add "const" and be done with it. v3: - un-constify atyfb, mb862xx, nvidia and uvesabf (0day) v2: - fix typo (Christophe de Dinechin) - use "static const" instead of "const static" in mx3fb.c - also constify smscufx.c Cc: linux-fbdev@vger.kernel.org Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/ce67f14435f3af498f2e8bf35ce4be11f7504132.1575390740.git.jani.nikula@intel.com
