when there's an error in 'ncq mode' the host has to read the ncq error
log (10h) to clear the error state. however, the ccb that is setup for
doing this doesn't setup the ccb so that the previous state is
cleared. if the ccb was previously used for an IO n_elems is set and
pm8001_ccb_task_free() treats this as the signal to go free a
scatter-gather list (that's already been freed).

Modified SATA abort handling with following steps:
1) Set device state as recovery.
2) Send phy reset.
3) Wait for reset completion.
4) After successful reset, abort all IO's to the device.
5) After aborting all IO's to device, set device state as operational.

As per SAM there is a status precedence, with any sense code 29/XX
taking second place just after an ACA ACTIVE status. Additionally, each
target might prefer to not queue any unit attention conditions, but just
report one. Due to the above, this will be that one with the highest
precedence. This results in the sense code 29/XX effectively
overwriting any other unit attention. Hence we should report the
power-on reset to userland so that it can take appropriate action.

introduced an off-by-one error in sg_ioctl(), which was fixed by commit

Unfortunately commit 4759df905a47 ("scsi: sg: factor out

When checking the model and vendor string we need to use the minimum
value of either string, otherwise we'll miss out on wildcard matches.
And we should take care when matching with zero size strings; results
might be unpredictable. With this patch the rules for matching devinfo
strings are as follows:
- Vendor strings must match exactly
- Empty Model strings will only match if the devinfo model
is also empty
- Model strings shorter than the devinfo model string will
not match
