Subject: [PATCH] staging: rtl8723bs: replace msleep with usleep_range for short delays
Date: Sat, 9 May 2026 13:37:27 +0530 [thread overview]
Message-ID: <20260509080727.21636-1-sridhar.arra.dev@gmail.com> (raw)
The checkpatch.pl tool warns that msleep() for values less than 20ms
can be inaccurate. This patch converts the 10ms msleep to
usleep_range(10000, 11000) to provide more precise timing using
high-resolution timers.
