From: Kristina Martšenko Date: Tue, 15 Jul 2014 23:30:19 +0000 (+0300) Subject: ARM: OMAP2+: remove DSP platform device X-Git-Tag: firefly_0821_release~176^2~3491^2~728 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=f65f6455fc082c7488af34f6955eb928903c3ae5;p=firefly-linux-kernel-4.4.55.git ARM: OMAP2+: remove DSP platform device It was added to support DSP Bridge. Since DSP Bridge was removed, and nothing else is using the platform device, remove it too.
