[PATCH] ASoC: intel: skl_rt286: Replace GFP_ATOMIC with GFP_KERNEL in skylake_audio_probe
From: Jia-Ju Bai
Date: Mon Apr 09 2018 - 06:49:58 EST
skylake_audio_probe() is never called in atomic context.
This function is only set as ".probe" in "struct platform_driver".
Despite never getting called from atomic context,
skylake_audio_probe() calls devm_kzalloc() with GFP_ATOMIC,
which waits busily for allocation.
GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL,
to avoid busy waiting and improve the possibility of sucessful allocation.
This is found by a static analysis tool named DCNS written by myself.
