Subject: staging/westbridge: convert cyasgadget to new udc core
X-Git-Tag: v3.1-rc1~232^2~123
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d8bfbf6e0d3eb5309e077eac004efe01e6146beb;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git

staging/westbridge: convert cyasgadget to new udc core

This is not compile tested as I failed at it. I added an #if 0 block
because I did not find the struct device of the device.
