From: Letu Ren <fantasquex@xxxxxxxxx> [ Upstream commit 92766c4628ea349c8ddab0cd7bd0488f36e5c4ce ] When calling the 'ql_wait_for_drvr_lock' and 'ql_adapter_reset', the driver has already acquired the spin lock, so the driver should not call 'ssleep' in atomic context. This bug can be fixed by using 'mdelay' instead of 'ssleep'. Reported-by: Letu Ren <fantasquex@xxxxxxxxx> Signed-off-by: Letu Ren <fantasquex@xxxxxxxxx> Signed-off-by: David S.
