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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
