media: ttusb-dec: Fix info-leak in ttusb_dec_send_command()
[ Upstream commit a10feaf8c464c3f9cfdd3a8a7ce17e1c0d498da1 ]
The function at issue does not always initialize each byte allocated
for 'b' and can therefore leak uninitialized memory to a USB device in
the call to usb_bulk_msg()
Use kzalloc() instead of kmalloc()
