EDAC/i5100: Fix error handling order in i5100_init_one()
When pci_get_device_func() fails, the driver doesn't need to execute pci_dev_put(). mci should still be freed, though, to prevent a memory leak. When pci_enable_device() fails, the error injection PCI device "einj" doesn't need to be disabled either. [ bp: Massage commit message, rename label to "bail_mc_free". ] Fixes: 52608ba205461 ("i5100_edac: probe for device 19 function 0") Signed-off-by: Dinghao Liu <dinghao.liu@zju.edu.cn> Signed-off-by: Borislav Petkov <bp@suse.de> Link: https://lkml.kernel.org/r/20200826121437.31606-1-dinghao.liu@zju.edu.cn
