Subject: s390/dasd: Reduce amount of messages for specific errors
X-Git-Tag: upstream/snapshot3+hdmi~4810^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f6f80340308cdcb84db45d3abf95f23d5b66051d;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

s390/dasd: Reduce amount of messages for specific errors

Whenever a request has been aborted internally by the driver
there is no sense data to be had. And printing lots of messages
stalls the system, so better to print out a short one-liner.
