Subject: USB: typec: tps6598x: Fix a memory leak in an error handling path
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cdd0cde8d8837de3d234bb08115d5f196e0ac8dd;p=linux.git

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

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