Subject: drivers/rtc/rtc-cmos.c: cmos_init(): don't ignore pnp_register_driver() return value
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13326
Prevents a null-pointer deref under the above-described circumstances.
pnp_unregister_driver() shouldn't oops the kernel either - that's a
different bug.
