hippi: Fix a Fix a possible sleep-in-atomic bug in rr_close The driver may sleep under a spinlock. The function call path is: rr_close (acquire the spinlock) free_irq --> may sleep To fix it, free_irq is moved to the place without holding the spinlock. This bug is found by my static analysis tool(DSAC) and checked by my code review. Signed-off-by: Jia-Ju Bai <baijiaju1990@163.com> Signed-off-by: David S. Miller <davem@davemloft.net>
