Subject: s390: Use ccw_device_get_id() in qeth/claw drivers
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=dc5bc0cabd1003b4fa358f0d54dfdc46585efb57;p=openwrt%2Fstaging%2Fblogic.git

s390: Use ccw_device_get_id() in qeth/claw drivers

Use ccw_device_get_id() to get a device number
instead of parsing the ccw device's bus id.
