Subject: [PATCH 2/2] pcmcia: limit pxa2xx_trizeps4 subdriver to trizeps4 platform
Date: Fri, 1 Apr 2011 13:28:46 +0400 [thread overview]
Message-ID: <1301650126-6992-2-git-send-email-dbaryshkov@gmail.com> (raw)
In-Reply-To: <1301650126-6992-1-git-send-email-dbaryshkov@gmail.com>
pxa2xx_trizeps4 tries to register pxa2xx-pcmcia device not checking whether
machine is really trizeps4, thus messing multi-machine kernels. Fix it up.
