Subject: um: Add BUG() to do_ops()'s error path
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=62179d47c2b1495bedc942b424e933a4b0f2ed51;p=linux-beck.git

um: Add BUG() to do_ops()'s error path

In case we encounter a bad operation in do_ops() something is really
broken and it's better to BUG().
