6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ilpo Järvinen <ilpo.jarvinen@xxxxxxxxxxxxxxx> commit 14cba6ace79627a57fb9058582b03f0ed3832390 upstream. amd_rng_mod_init() uses pci_read_config_dword() that returns PCIBIOS_* codes. The return code is then returned as is but amd_rng_mod_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.
