Subject: [PATCH] softingcs: Fix memleak on registration failure in softingcs_probe

From: Miaoqian Lin <[email-masked]>
Date: Sat, 8 Jan 2022 09:25:51 +0000

In case device registration fails during module initialisation, the
platform device structure needs to be freed using platform_device_put()
to properly free all resources (e.g. the device name).

Fixes: 0a0b7a5f7a04 ("can: add driver for Softing card")
