[alsa-devel] [BUG] sound/soc/samsung: a possible sleep-in-atomic bugs in s3c_pcm_hw_params

According to sound/soc/samsung/pcm.c, the kernel module may sleep under a spinlock. The function call path is: s3c_pcm_hw_params (acquire the spinlock) clk_get_rate clk_core_get_rate clk_prepare_lock mutex_lock --> may sleep

I do not find a good way to fix it, so I only report. This possible bug is found by my static analysis tool (DSAC) and my code review.

Thanks, Jia-Ju Bai
