Subject: UHCI: don't stop at an Iso error
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7ceb932f489e86b555258e5f7d7f061f9c1863eb;p=linux-beck.git

UHCI: don't stop at an Iso error

Unlike other sorts of endpoint queues, Isochronous queues don't stop
when an error is encountered.  This patch (as772) fixes the scanning
routine in uhci-hcd, to make it keep on going when it finds an Iso
error.
