From 7cbc9e8fe6ccbc47604a91901620c67bc538e152 Mon Sep 17 00:00:00 2001 From: Julian Wiedmann Date: Tue, 11 Jun 2019 18:37:51 +0200 Subject: [PATCH] s390/qeth: restart pending READ cmd from callback The completion of a pending READ cmd is processed via qeth_issue_next_read_cb(). Let this callback also start the next READ cmd, instead of hardcoding that step into the IRQ handler. While at it remove the check of the channel state, __qeth_issue_next_read() already does this.
