[PATCH] USB: typec: tps6598x: Fix a memory leak in an error handling path

From: Christophe JAILLET
Date: Mon Oct 30 2023 - 02:57:08 EST


All error handling end to the error handling path, except these ones.
Go to 'release_fw' as well here, otherwise 'fw' is leaking.

Fixes: 7e7a3c815d22 ("USB: typec: tps6598x: Add TPS25750 support")
