Subject: [PATCH net-next 04/13] s390/qeth: restart pending READ cmd from callback
Date: Tue, 11 Jun 2019 18:37:51 +0200	[thread overview]
Message-ID: <20190611163800.64730-5-jwi@linux.ibm.com> (raw)
In-Reply-To: <20190611163800.64730-1-jwi@linux.ibm.com>

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.
