Subject: [PATCH] fbdev: fixed typo in hw_bitblt_1 and hw_bitblt_2
Date: Fri, 1 Mar 2024 14:35:43 +0300 [thread overview]
Message-ID: <20240301113543.24312-1-a.burakov@rosalinux.ru> (raw)
There are some actions with value 'tmp' but 'dst_addr' is checked instead.
It is obvious that a copy-paste error was made here and the value
of variable 'tmp' should be checked here.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: f7018c213502 ("video: move fbdev to drivers/video/fbdev")
Signed-off-by: Aleksandr Burakov <a.burakov@rosalinux.ru>
