Subject: [PATCH net 3/8] can: sja1000_isa: sja1000_isa_probe(): add missing free_sja1000dev()

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

Add the missing free_sja1000dev() before return from
sja1000_isa_probe() in the register_sja1000dev() error handling case.

In addition, remove blanks before goto labels.
