Subject: [PATCH v3 04/43] fbdev/deferred-io: Test screen_buffer for vmalloc'ed memory
Date: Fri, 19 Apr 2024 10:28:57 +0200 [thread overview]
Message-ID: <20240419083331.7761-5-tzimmermann@suse.de> (raw)
In-Reply-To: <20240419083331.7761-1-tzimmermann@suse.de>
Framebuffers in virtual memory are available via screen_buffer. Use
it instead of screen_base and avoid the type casting.
