Subject: [PATCH v2] clk: imx: scu: Use pm_runtime_resume_and_get to fix pm_runtime_get_sync() usage
Date: Fri, 22 Apr 2022 09:33:16 +0800 [thread overview]
Message-ID: <20220422013317.30362-1-linmq006@gmail.com> (raw)
In-Reply-To: <20220422012059.52267C385A5@smtp.kernel.org>
If the device is already in a runtime PM enabled state
pm_runtime_get_sync() will return 1.
Also, we need to call pm_runtime_put_noidle() when pm_runtime_get_sync()
fails, so use pm_runtime_resume_and_get() instead. this function
will handle this.
Fixes: 78edeb080330 ("clk: imx: scu: add runtime pm support")
