Mateusz Guzik 1f55176763 ipc: fix compat msgrcv with negative msgtyp ... commit e7ca2552369c1dfe0216c626baf82c3d83ec36bb upstream. Compat function takes msgtyp argument as u32 and passes it down to do_msgrcv which results in casting to long, thus the sign is lost and we get a big positive number instead. Cast the argument to signed type before passing it down.
