Subject: [PATCH 11/12] drm/amd/display: Remove duplicated CalculateWriteBackDISPCLK
Date: Thu, 14 Jul 2022 13:45:06 -0300	[thread overview]
Message-ID: <20220714164507.561751-11-mairacanal@riseup.net> (raw)
In-Reply-To: <20220714164507.561751-1-mairacanal@riseup.net>

The functions dml30_CalculateWriteBackDISPCLK and
dml31_CalculateWriteBackDISPCLK are identical. Therefor, to avoid
code duplication, dml31_CalculateWriteBackDISPCLK is removed and
replaced by dml30_CalculateWriteBackDISPCLK.
