From: Selby Mashiki <[email protected]> udelay() busy-waits for the specified duration, consuming CPU cycles unnecessarily. usleep_range() is preferred for delays that can sleep, as it allows the scheduler to run other tasks during the wait.
Replace two instances of udelay(100) with usleep_range(100, 200) to use the preferred sleeping delay function.
