Subject: [PATCH 10/12] ASoC: cs42l42: Remove redundant pll_divout member
Date: Tue, 10 Aug 2021 16:37:57 +0100 [thread overview]
Message-ID: <20210810153759.24333-11-rf@opensource.cirrus.com> (raw)
In-Reply-To: <20210810153759.24333-1-rf@opensource.cirrus.com>
Now that struct cs42l42_private has pll_config, the current PLL
configuration can be looked up directly in pll_ratio_table. This
makes the pll_divout member of cs42l42_private redundant since it
was only a copy of the value from pll_ratio_table.
