[PATCH] libata: check if port is disabled after internal command
libata core is being changed to disallow port/device disable on lower
layers. However, some LLDDs (sata_mv) directly disable port on
command failure. This patch makes ata_exec_internal() check whether a
port got disabled after an internal command. If it is, AC_ERR_SYSTEM
is added to err_mask and the port gets re-enabled.
As internal command failure results in device disable for drivers
which don't implement newer reset/EH callbacks, this change results in
no behavior change for single device per port controllers. For
slave-possible LLDDs which disable port on command failure, (1) such
drivers don't exist currently, (2) issuing command to the other device
of once-disabled port shouldn't result in catastrophe even if such
driver exists. So, this should be enough as a temporary measure.
