2021-07-20scsi: qedi: Fix null ref during abort handlingMike Christie
[ Upstream commit 5777b7f0f03ce49372203b6521631f62f2810c8f ] If qedi_process_cmd_cleanup_resp finds the cmd it frees the work and sets list_tmf_work to NULL, so qedi_tmf_work should check if list_tmf_work is non-NULL when it wants to force cleanup.

2020-10-29scsi: qedi: Fix list_del corruption while removing active I/ONilesh Javali
[ Upstream commit 28b35d17f9f8573d4646dd8df08917a4076a6b63 ] While aborting the I/O, the firmware cleanup task timed out and driver deleted the I/O from active command list. Some time later the firmware sent the cleanup task response and driver again deleted the I/O from active command list causing firmware to send completion for non-existent I/O and list_del corruption of active command list. Add fix to check if I/O is present before deleting it from the active command list to ensure firmware sends valid I/O completion and protect against list_del corruption.

2019-04-08drivers: Remove explicit invocations of mmiowb()Will Deacon
mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.
