Subject: [PATCH v5 5/5] arch/powerpc: Call internal __phys_mem_access_prot() in fbdev code
Date: Fri, 22 Sep 2023 10:04:59 +0200 [thread overview]
Message-ID: <20230922080636.26762-6-tzimmermann@suse.de> (raw)
In-Reply-To: <20230922080636.26762-1-tzimmermann@suse.de>
Call __phys_mem_access_prot() from the fbdev mmap helper
pgprot_framebuffer(). Allows to avoid the file argument of NULL.
