Subject: [PATCH] staging: rtl8723bs: replace msleep with usleep_range for 1ms delay
Date: Sat,  9 May 2026 15:10:59 +0530	[thread overview]
Message-ID: <20260509094059.22101-1-sridhar.arra.dev@gmail.com> (raw)

The checkpatch.pl tool warns that msleep() for values less than 20ms
can be inaccurate and oversleep. This patch converts the 1ms msleep
to usleep_range(1000, 2000) to ensure more precise timing in the
power control path.
