[ Upstream commit eb367d875f94a228c17c8538e3f2efcf2eb07ead ]
In 'rt2880_pmx_group_enable' driver is printing an error and returning -EBUSY if a pin has been already enabled. This begets anoying messages in the caller when this happens like the following:
rt2880-pinmux pinctrl: pcie is already enabled mt7621-pci 1e140000.pcie: Error applying setting, reverse things back
To avoid this just print the already enabled message in the pinctrl driver and return 0 instead to not confuse the user with a real bad problem.
