serial: sunsab: Fix error handling in sunsab_init()
[ Upstream commit1a6ec673fb
] The sunsab_init() returns the platform_driver_register() directly without checking its return value, if platform_driver_register() failed, the allocated sunsab_ports is leaked. Fix by free sunsab_ports and set it to NULL when platform_driver_register() failed. Fixes:c4d37215a8
