This patch fixes the checkpatch.pl warning: "WARNING: do not add new typedefs". Hiding a variables of type 'struct' is not always a good idea,because when we passing them as parameters we tempt to forget that in this proces we work with stack memory and allocatting struct on stack is something that we should manage carefuly. It is also delete the '_t' from the name of the structs and treat a line over 80 character issue in ddk750_mode.c, that appear after my modification.
