  Replace the use of udelay by usleep_range as suggested by checkpatch:

CHECK: usleep_range is preferred over udelay; see Documentation/timers/timers-howto.rst
+               udelay(30);

CHECK: usleep_range is preferred over udelay; see Documentation/timers/timers-howto.rst
+               udelay(50);

This isn't useful.  Please read the Documentation/timers.
