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.
