Title
mmc: sdhci-pci: Fix possible memory leak caused by missing pci_dev_put()
Summary
In the Linux kernel, the following vulnerability has been resolved: mmc: sdhci-pci: Fix possible memory leak caused by missing pci_dev_put() pci_get_device() will increase the reference count for the returned pci_dev. We need to use pci_dev_put() to decrease the reference count before amd_probe() returns. There is no problem for the 'smbus_dev == NULL' branch because pci_dev_put() can also handle the NULL input parameter case.
