Subject: [PATCH v4 5/5] arch/powerpc: Call internal __phys_mem_access_prot() in fbdev code
Date: Tue, 12 Sep 2023 15:49:03 +0200 [thread overview]
Message-ID: <20230912135050.17155-6-tzimmermann@suse.de> (raw)
In-Reply-To: <20230912135050.17155-1-tzimmermann@suse.de>
Call __phys_mem_access_prot() from the fbdev mmap helper
pgprot_framebuffer(). Allows to avoid the file argument of NULL.
