CVE-2022-50039

In the Linux kernel, the following vulnerability has been resolved:

stmmac: intel: Add a missing clkdisableunprepare() call in intelethpci_remove()

Commit 09f012e64e4b ("stmmac: intel: Fix clock handling on error and remove paths") removed this clkdisableunprepare()

This was partly revert by commit ac322f86b56c ("net: stmmac: Fix clock handling on remove path") which removed this clkdisableunprepare() because: " While unloading the dwmac-intel driver, clkdisableunprepare() is being called twice in stmmacdvrremove() and intelethpci_remove(). This causes kernel panic on the second call. "

However later on, commit 5ec55823438e8 ("net: stmmac: add clocks management for gmac driver") has updated stmmacdvrremove() which do not call clkdisableunprepare() anymore.

So this call should now be called from intelethpci_remove().
