[PATCH 6/8] pinctrl: at91: replace dev_get_drvdata with device_get_match_data

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

dev_get_drvdata() and device_get_match_data() can already deal with both
OF and non-OF match data, so at91_pinctrl_get_driver_data only adds some
unneeded complexity. Remove it and while at it switch to the less
error-prone device_get_match_data.
