4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mario Limonciello <mario.limonciello@xxxxxxx>
commit 87b549efcb0f7934b0916d2a00607a878b6f1e0f upstream.
On some systems amd_pinconf_set() is called with parameters
0x8 (PIN_CONFIG_DRIVE_PUSH_PULL) or 0x14 (PIN_CONFIG_PERSIST_STATE)
which are not supported by pinctrl-amd.
Don't show an err message when called with an invalid parameter,
downgrade this to debug instead.
