Subject: [PATCH 0/4] ppc, fbdev: Clean up fbdev mmap helper
Date: Fri,  1 Sep 2023 16:16:32 +0200	[thread overview]
Message-ID: <20230901142659.31787-1-tzimmermann@suse.de> (raw)

Refactor fb_pgprotect() in PowerPC to work without struct file. Then
clean up and rename fb_pgprotect(). This change has been discussed at
[1] in the context of refactoring fbdev's mmap code.

The first three patches adapt PowerPC's internal interfaces to
provide a phys_mem_access_prot() that works without struct file. Neither
the architecture code or fbdev helpers need the parameter.

Patch 4 replaces fbdev's fb_pgprotect() with fb_pgprot_device() on
all architectures. The new helper with its stream-lined interface
enables more refactoring within fbdev's mmap implementation.
