Subject: [PATCH v2 1/4] ASoC: wm_adsp: Use usleep_range for short delay
Date: Mon, 26 Sep 2016 10:15:22 +0100	[thread overview]
Message-ID: <1474881325-9466-1-git-send-email-ckeepax@opensource.wolfsonmicro.com> (raw)

Replace the 1ms msleep in wm_adsp2_ena with a usleep_range, as per
normal guidance on delay functions. Also tighten up the delay a little
as 1ms was quite generous.
