Input: imx_keypad - only set enabled columns to open-drain 2012-11-25T08:10:18+00:00 Andreas Pretzsch apr@cn-eng.de 2012-11-25T07:31:38+00:00 92aab96034c2cdf11eb61a6b14409c2da8e5158d In imx_keypad_inhibit(), all 8 columns were set to open-drain, in contrast to the rest of the driver, where only the enabled columns are modified/used. Contrary to the normal expectation, this also affects column I/Os not even mapped via IOMUX to the KPP hardware module but used as a GPIO. Therefore only init enabled columns to open-drain and leave all others with their default reset value of 0, i.e. totem-pole.
