Subject: [PATCH 1/5] ASoC: stm32: properly get clk from the provider
Date:   Sat, 10 Apr 2021 13:13:52 +0200

Instead of using the clk embedded in the clk_hw (which is meant to go
away), a clock provider which need to interact with its own clock should
request clk reference through the clock provider API.
