Subject: [PATCH] floppy: check_events callback should not return a negative number
Date: Mon, 28 Jan 2019 09:06:46 +0000 [thread overview]
Message-ID: <20190128090646.44747-1-yuyufen@huawei.com> (raw)
Since .check_events interface return an unsigned int value,
floppy_check_events() should not return a negative error number.
Otherwise, disk_check_events() may process wiht an unexpected path.
fixes: a0c80efe5956 ("floppy: fix lock_fdc() signal handling")
