Jia-Ju Bai bffa9b1cc6 staging: dgnc: Fix a sleep-in-atomic-context bug in cls_assert_modem_signals() ... The driver may sleep with holding a spinlock. The function call path (from bottom to top) in Linux-4.17 is: [FUNC] usleep_range drivers/staging/dgnc/dgnc_cls.c, 391: usleep_range in cls_assert_modem_signals drivers/staging/dgnc/dgnc_cls.c, 449: cls_assert_modem_signals in cls_copy_data_from_queue_to_uart drivers/staging/dgnc/dgnc_cls.c, 406: _raw_spin_lock_irqsave in cls_copy_data_from_queue_to_uart To fix this bug, usleep_range() is replaced with udelay(). This bug is found by my static analysis tool DSAC. Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2018-09-18 13:29:10 +02:00
