[PATCH] fbdev: mmp: Use devm_clk_get_enabled() helpers
From: ying zuxin <hidden>
Date: 2024-08-23 12:30:41
Also in:
dri-devel, lkml
Subsystem:
framebuffer layer, the rest · Maintainers:
Helge Deller, Linus Torvalds
The devm_clk_get_enabled() helpers:
- call devm_clk_get()
- call clk_prepare_enable() and register what is needed in order to
call clk_disable_unprepare() when needed, as a managed resource.
This simplifies the code and avoids the calls to clk_disable_unprepare().
