Subject: [PATCH] fbdev: sm501fb: use memset_io
Date: Tue, 10 Feb 2015 12:49:32 +0000 [thread overview]
Message-ID: <1423571852-14511-1-git-send-email-sudipm.mukherjee@gmail.com> (raw)
we should really be using memset_io() instead of using memset() as
this is actually io space mapped into our memory.
