Subject: [PATCH] pinctrl: initialise nsp-mux earlier.
Date: Wed,  1 Jul 2020 09:29:58 +1200
Message-ID: <20200630212958.24030-1-mark.tomlinson@alliedtelesis.co.nz> (raw)

The GPIO specified in the DTS file references the pinctrl, which is
specified after the GPIO. If the GPIO is initialised before pinctrl,
an error message for the -EPROBE_DEFER ends up in the kernel log. Even
though the probe will succeed when the driver is re-initialised, the
error can be scary to end users. To fix this, change the time the
pinctrl is probed, so that it is always before the GPIO driver.
