[PATCH 1/8] usb: typec: ucsi: yoga-c630: fix error and remove paths

[Dmitry Baryshkov]

Fix memory leak and call ucsi_destroy() from the driver's remove
function and probe's error path in order to remove debugfs files and
free the memory. Also call yoga_c630_ec_unregister_notify() in the
probe's error path.

Fixes: 2ea6d07efe53 ("usb: typec: ucsi: add Lenovo Yoga C630 glue driver")
