Subject: [POWERPC] Convert media-bay.c to use the kthread API
X-Git-Tag: v2.6.25-rc1~1131^2~281
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=33f6e7940691b1c92b276148c48a9551ac07f11d;p=linux-2.6-omap-h63xx.git

[POWERPC] Convert media-bay.c to use the kthread API

We aren't supposed to use kernel_thread directly in drivers any more,
and in fact using kthread_run is a bit simpler.
