Subject: pinctrl: lpc18xx: fix schmitt trigger setup
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=681ccdcc756f17f847beba5ac4cd3d03e0949489;p=linux-beck.git

pinctrl: lpc18xx: fix schmitt trigger setup

The param_val variable is what determines if schmitt
trigger is enabled on a pin or not. A typo here mean
that schmitt trigger was always enabled for standard
and i2c pins.
