Subject: [PATCH net 4/8] can: cc770: cc770_isa_probe(): add missing free_cc770dev()

From: Zhang Changzhong <zhangchangzhong@...wei.com>

Add the missing free_cc770dev() before return from cc770_isa_probe()
in the register_cc770dev() error handling case.

In addition, remove blanks before goto labels.
