rtc: r7301: Fix a possible sleep-in-atomic bug in rtc7301_set_time The driver may sleep under a spinlock. The function call path is: rtc7301_set_time (acquire the spinlock) usleep_range --> may sleep To fix it, usleep_range is replaced with udelay. This bug is found by my static analysis tool(DSAC) and checked by my code review.
