Subject: rfkill: detect bogus double-registering (v2)
X-Git-Tag: v2.6.28-rc1~717^2~436
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=02589f60510030a3c1496e7a8c511e4f674ef5ff;p=pandora-kernel.git

rfkill: detect bogus double-registering (v2)

Detect and abort with -EEXIST if rfkill_register is called twice on the
same rfkill struct.  And WARN_ON(it) for good measure.

While at it, flag when we are adding the first switch of a type, we will
need that information later.
