Subject: [media] gs1662: drop kfree for memory allocated with devm_kzalloc

From: Wei Yongjun <weiyongjun1@huawei.com>

commit df94121f02ecce435d6b5277071eb94b764caa89 upstream.

It's not necessary to free memory allocated with devm_kzalloc
and using kfree leads to a double free.

Fixes: 7aae6e2df127 ("[media] Add GS1662 driver, a video serializer")
