Ma Ke 5fb232c763 drm/tegra: dc: Fix reference leak in tegra_dc_couple() ...

commit 4c5376b4b1 upstream.

driver_find_device() calls get_device() to increment the reference
count once a matching device is found, but there is no put_device() to
balance the reference count. To avoid reference count leakage, add
put_device() to decrease the reference count.

Found by code review.
