Include <linux/io.h> to avoid depending on <linux/backlight.h>
for including it. Declares __raw_readb() and __raw_writeb().
Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de>
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202510282206.wI0HrqcK-lkp@intel.com/
Fixes: 243ce64b2b ("backlight: Do not include <linux/fb.h> in header file")
