scsi: ufs: core: Improve SCSI abort handling
[ Upstream commit 3ff1f6b6ba6f97f50862aa50e79959cc8ddc2566 ]
The following has been observed on a test setup:
WARNING: CPU: 4 PID: 250 at drivers/scsi/ufs/ufshcd.c:2737 ufshcd_queuecommand+0x468/0x65c
Call trace:
ufshcd_queuecommand+0x468/0x65c
scsi_send_eh_cmnd+0x224/0x6a0
scsi_eh_test_devices+0x248/0x418
scsi_eh_ready_devs+0xc34/0xe58
scsi_error_handler+0x204/0x80c
kthread+0x150/0x1b4
ret_from_fork+0x10/0x30
That warning is triggered by the following statement:
WARN_ON(lrbp->cmd);
Fix this warning by clearing lrbp->cmd from the abort handler.
