[PATCH] staging: fbtft: Replace udelay with preferred usleep_range

From: John B. Wyatt IV
Date: Sun Mar 29 2020 - 05:22:43 EST


Fix style issue with usleep_range being reported as preferred over
udelay.

Issue reported by checkpatch.

Please review.

As written in Documentation/timers/timers-howto.rst udelay is the
generally preferred API. hrtimers, as noted in the docs, may be too
expensive for this short timer.

Are the docs out of date, or, is this a checkpatch issue?
