Subject: [PATCH] drm/amd/display: Fix boolean expression in get_surf_rq_param
Date: Thu, 3 Jan 2019 13:48:45 -0600 [thread overview]
Message-ID: <20190103194845.GA26175@embeddedor> (raw)
Fix boolean expression by using logical AND operator '&&'
instead of bitwise operator '&'.
This issue was detected with the help of Coccinelle.
