Subject: rt2800: replace mdelay by usleep on vco calibration.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=eb79a8fe94c8a16687112e0a3abcce8225447f6f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

rt2800: replace mdelay by usleep on vco calibration.

This procedure can sleep, hence mdelay is not needed.
