Subject: [PATCH] fbdev: i740fb: use memset_io() to clear screen
Date: Sun, 10 Apr 2022 22:28:33 +0200 [thread overview]
Message-ID: <20220410202833.26608-1-linux@zary.sk> (raw)
sparse complains that using memset() on __iomem pointer is wrong:
incorrect type in argument 1 (different address spaces)
Use memset_io() to clear screen instead.
Tested on real i740 cards.
