From 12fc286f84b19ba61a8f64c80dc683cfb19f0251 Mon Sep 17 00:00:00 2001 From: Julian Wiedmann Date: Tue, 20 Aug 2019 16:46:36 +0200 Subject: s390/qeth: propagate length of processed cmd IO data to callback When an cmd IO completes in qeth_irq(), calculate how much data was processed by the device and pass this value to the cmd's callback. This allows cmds that retrieve data from the device to check whether sufficient data was received, so we do that in qeth_read_conf_data_cb().
