Subject: [PATCH v2 1/2] drm/amd/display: dc_link: code clean up on
 enable_link_dp function
Message-ID: <922a2d0df348e72588405dedd4f9a296448f51c3.1582907436.git.melissa.srw@gmail.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Coding style clean up on enable_link_dp function as suggested by
checkpatch.pl:

CHECK: Lines should not end with a '('
WARNING: line over 80 characters
WARNING: suspect code indent for conditional statements (8, 24)
CHECK: braces {} should be used on all arms of this statement
ERROR: else should follow close brace '}'
CHECK: Comparison to NULL could be written
       "link->preferred_training_settings.fec_enable"
