staging: tidspbridge: protect dmm_map properly
commit ab42abf33a3efdf754710a0a513c00c40854cd61 upstream.
We need to protect not only the dmm_map list, but the individual
map_obj's, otherwise, we might be building the scatter-gather list with
garbage. So, use the existing proc_lock for that.
I observed race conditions which caused kernel panics while running
stress tests, also, Tuomas Kulve found it happening quite often in
Gumstix Over. This patch fixes those.
