[PATCH -next] bus: imx-weim: Use devm_clk_get_enabled() helper function
From: Jinjie Ruan <hidden>
Date: 2023-08-25 07:20:15
Subsystem:
the rest · Maintainer:
Linus Torvalds
The devm_clk_get_enabled() helper:
- calls devm_clk_get()
- calls clk_prepare_enable() and registers what is needed in order to
call clk_disable_unprepare() when needed, as a managed resource.
This simplifies the code.
