X-Git-Tag: v3.12-rc1~31390^2~21^2~15 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=758976f9a55cb22ddc602a0690d67f9546e3e43f;p=kernel%2Fkernel-generic.git [S390] cio: Catch operand exceptions on stsch. If we have a subchannel id which has been generated via for_each_subchannel(), it might contain an invalid subchannel set id. We need to catch the ensuing operand exception by using stsch_err() instead of stsch() in all possible cases.
