Re: [PATCH 1/1] staging: media: soc_camera: Adding parentheses to macro defination at line 241, Clearing alignment issues at lines 410 and 1270, fixing return values at EPOLLERR

The soc_camera driver obsolete and depends on BROKEN. And in fact, I'm
working on removing it. So I'll drop this patch for those reasons.
