mmc: sdhci-pci-o2micro: Convert PCIBIOS_* return codes to errnos
sdhci_pci_o2_probe() uses pci_read_config_{byte,dword}() that return PCIBIOS_* codes. The return code is then returned as is but as sdhci_pci_o2_probe() is probe function chain, it should return normal errnos. Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal errno before returning them. Add a label for read failure so that the conversion can be done in one place rather than on all of the return statements. Fixes: 3d757dd ("mmc: sdhci-pci-o2micro: add Bayhub new chip GG8 support for UHS-I") Fixes: d599005 ("mmc: sdhci-pci-o2micro: Add missing checks in sdhci_pci_o2_probe") Fixes: 706adf6 ("mmc: sdhci-pci-o2micro: Add SeaBird SeaEagle SD3 support") Fixes: 01acf69 ("mmc: sdhci-pci: add support of O2Micro/BayHubTech SD hosts") Fixes: 26daa1e ("mmc: sdhci: Disable ADMA on some O2Micro SD/MMC parts.")
