From eb367d875f94a228c17c8538e3f2efcf2eb07ead Mon Sep 17 00:00:00 2001 From: Sergio Paracuellos Date: Fri, 4 Jun 2021 07:53:37 +0200 Subject: pinctrl: ralink: rt2880: avoid to error in calls is pin is already enabled 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.
