Subject: [PATCH] staging: rtl8723bs: Replace msleep with usleep_range
Date: Fri, 20 Mar 2026 01:24:37 +0530 [thread overview]
Message-ID: <20260319195437.53068-1-ayushmukkanwar@gmail.com> (raw)
The checkpatch.pl script flagged a warning regarding the use of
msleep() for less than 20ms. msleep() relies on jiffies and can
be inaccurate for short durations, leading to inefficient delays.
Replace msleep(10) with usleep_range(10000, 12000) to allow for
timer coalescing. This gives the kernel scheduler a 2ms window
to group wakeups, improving overall system power efficiency
while maintaining the required 10ms minimum delay.
