Subject: [PATCH 1/2] gpio: amd8111: Convert PCIBIOS_* return codes to errnos
amd_gpio_init() uses pci_read_config_dword() that returns PCIBIOS_*
codes. The return code is then returned as is but amd_gpio_init() is
a module init function that should return normal errnos.
Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal
errno before returning it from amd_gpio_init().
Fixes: f942a7de047d ("gpio: add a driver for GPIO pins found on AMD-8111 south bridge chips")
