Subject: [PATCH] staging: rtl8723bs: replace msleep with usleep_range for small delays

From: Fu Zang <t1468150755@...il.com>

The msleep() function is not recommended for delays shorter than 20ms
as it may sleep considerably longer than requested.

This patch replaces msleep(10) with usleep_range(10000, 11000) to
provide more precise delay control while allowing the timer subsystem
to coalesce wakeups.
