leds: ss4200: Convert PCIBIOS_* return codes to errnos

Browse source

commit ce068e8397 upstream.

ich7_lpc_probe() uses pci_read_config_dword() that returns PCIBIOS_*
codes. The error handling code assumes incorrectly it's a normal errno
and checks for < 0. The return code is returned from the probe function
as is but probe functions should return normal errnos.

Remove < 0 from the check and convert PCIBIOS_* returns code using
pcibios_err_to_errno() into normal errno before returning it.
