[PATCH 5.10.y 3/4] platform/chrome: cros_ec: remove unneeded label and if-condition

[Sasha Levin <sashal@kernel.org>]

From: Tzung-Bi Shih <tzungbi@kernel.org>

[ Upstream commit 554ec02c97254962bbb0a8776c3160d294fc7e51 ]

Both `ec_dev->ec` and `ec_dev->pd` are initialized to NULL at the
beginning of cros_ec_register().  Also, platform_device_unregister()
takes care if the given platform_device is NULL.

Remove the unneeded goto-label and if-condition.
