Subject: [PATCH v2 4/5] fbdev: Include <linux/io.h> in drivers
Date: Fri, 28 Apr 2023 11:27:10 +0200	[thread overview]
Message-ID: <20230428092711.406-5-tzimmermann@suse.de> (raw)
In-Reply-To: <20230428092711.406-1-tzimmermann@suse.de>

Fbdev's main header file, <linux/fb.h>, includes <asm/io.h> to get
declarations of I/O helper functions. From these declaratons, it later
defines framebuffer I/O helpers, such as fb_{read,write}[bwlq]() or
fb_memset().

The framebuffer I/O helpers pre-date Linux' current I/O code and will
be replaced by regular I/O helpers. Prepare this change by adding an
include statement for <linux/io.h> to all source files that use the
framebuffer I/O helpers. They will still get declarations of the I/O
functions even after <linux/fb.h> has been cleaned up. Driver source
files that already include <asm/io.h> convert to <linux/io.h>.
