mmc: sdhci-pci: Convert PCIBIOS_* return codes to errnos
commit ebc4fc34eae8ddfbef49f2bdaced1bf4167ef80d upstream. jmicron_pmos() and sdhci_pci_probe() use pci_{read,write}_config_byte() that return PCIBIOS_* codes. The return code is then returned as is by jmicron_probe() and sdhci_pci_probe(). Similarly, the return code is also returned as is from jmicron_resume(). Both probe and resume functions should return normal errnos. Convert PCIBIOS_* returns code using pcibios_err_to_errno() into normal errno before returning them the fix these issues. Fixes: 7582041ff3d4 ("mmc: sdhci-pci: fix simple_return.cocci warnings") Fixes: 45211e215984 ("sdhci: toggle JMicron PMOS setting") Cc: stable@vger.kernel.org Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Acked-by: Adrian Hunter <adrian.hunter@intel.com> Link: https://lore.kernel.org/r/20240527132443.14038-1-ilpo.jarvinen@linux.intel.com Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
