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. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
