Subject: [PATCH 3/4] arch/powerpc: Call internal __phys_mem_access_prot() in fbdev code
Date: Fri, 1 Sep 2023 16:16:35 +0200 [thread overview]
Message-ID: <20230901142659.31787-4-tzimmermann@suse.de> (raw)
In-Reply-To: <20230901142659.31787-1-tzimmermann@suse.de>
Call __phys_mem_access_prot() from the fbdev mmap helper fb_pgprotect().
Allows us to avoid the file argument, which can then be removed from
fB_pgprotect() entirely. No other architecture uses the parameter.
