ulseep_range() uses hrtimers and provides no advantage over msleep() for larger delays. For this large delay msleep() is preferable.
Fixes: commit d3cb2de2479b ("ASoC: rt5659: add rt5659 codec driver") Link: http://lkml.org/lkml/2017/1/11/377 Signed-off-by: Nicholas Mc Guire hofrat@osadl.org ---
Problem was found by cocinelle script.
Patch was compile tested with: x86_64_defconfig + CONFIG_COMPILE_TEST=y SND_SOC=m + SND_SOC_ALL_CODECS=m (implies SND_SOC_RT5659=m) (44 sparse warnings - fixed in a seperate patches)
