Subject: [PATCH v1 2/5] usb: pxa27x_udc: Use devm_clk_get_enabled() helpers
Date: Thu, 22 Aug 2024 12:07:27 +0800	[thread overview]
Message-ID: <20240822040734.29412-3-liulei.rjpt@vivo.com> (raw)
In-Reply-To: <20240822040734.29412-1-liulei.rjpt@vivo.com>

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 calls to clk_disable_unprepare().

---
v0 -> v1
Incorrect usage of clk_prepare_enable() should be 
corrected to devm_clk_get_enabled().
