Subject: [PATCH] s390: ccw device reconnect oops.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e5945b4f605d1479d5b44252a2c691168c5d38d6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] s390: ccw device reconnect oops.

Search for a disconnect ccw_device on the ccw bus rather than on the css
bus (was a typo in patch I did for the klist conversion).  A cast to an
embedding ccw_device from an embedded device in a struct subchannel will
lead us to oopses.
