The change reorganized twl_direction_out() and twl_set() and swapped the function names around in the process. While doing that, a bug got introduced that's not obvious while reading the patch as it appears as no change to the code. The bug is we now call function twl4030_set_gpio_dataout() twice in both twl_direction_out() and twl_set(). Instead, we should first call twl_direction_out() in twl_direction_out() followed by twl4030_set_gpio_dataout() in twl_set(). This regression probably has gone unnoticed for a long time as the bootloader may have set the GPIO direction properly in many cases. This fixes at least the LCD panel not turning on omap3 LDP for example.
