Input: tegra-kbc - correct call to input_free_device
If kzalloc for kbc fails, then we have NULL pointer dereference while calling input_free_device(kbc->idev) in the error handling. So it is safer to always use the original name, input_dev. Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
