From 2589bd8242d74430b7a91109cfe59f2e2173e1bd Mon Sep 17 00:00:00 2001 From: Jia-Ju Bai Date: Mon, 9 Apr 2018 18:48:10 +0800 Subject: [PATCH] ASoC: intel: cht_bsw_max98090_ti: Replace GFP_ATOMIC with GFP_KERNEL in snd_cht_mc_probe snd_cht_mc_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, snd_cht_mc_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.
