Subject: [PATCH] amdgpu_connector_set_property, fix error branch not return errno
Date: Sat, 18 Apr 2020 02:27:20 -0700	[thread overview]
Message-ID: <1587202042-115745-1-git-send-email-bernard@vivo.com> (raw)

The "if(!encoder)" branch return the same value 0 of the success
branch, maybe return -EINVAL is more better.
