ts_format.reserved is not used anywhere yet, but the compiler generates a 
warning when the struct's (uninitialized) field is being copied around

drivers/hid/intel-ish-hid/ipc/ipc.c: In function ‘write_ipc_from_queue’:
drivers/hid/intel-ish-hid/ipc/ipc.c:316: warning: ‘ts_format.reserved’ may be used uninitialized in this function

Avoid this by force-initializing the field to zero.
