[PATCH v2 1/2] drm/amd/display: dc_link: code clean up on enable_link_dp function

From: Melissa Wen
Date: Fri Feb 28 2020 - 11:41:56 EST


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"
