Vlad Tsyrklevich f134f703dd omap2fb: Fix stack memory disclosure ... commit a01421e448 upstream. Using [1] for static analysis I found that the OMAPFB_QUERY_PLANE, OMAPFB_GET_COLOR_KEY, OMAPFB_GET_DISPLAY_INFO, and OMAPFB_GET_VRAM_INFO cases could all leak uninitialized stack memory--either due to uninitialized padding or 'reserved' fields. Fix them by clearing the shared union used to store copied out data.
