Subject: s390/qeth: restart pending READ cmd from callback
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7cbc9e8fe6ccbc47604a91901620c67bc538e152;p=openwrt%2Fstaging%2Fblogic.git

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.
