Subject: [PATCH V2 8/9] pm80xx : panic on ncq error cleaning up the read log.
Date: Wed, 18 Feb 2015 05:06:49 +0530 [thread overview]
Message-ID: <20150217233650.9091-9-Viswas.G@microsemi.com> (raw)
In-Reply-To: <20150217233650.9091-1-Viswas.G@microsemi.com>
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 free-ed).
