This small series adds modularization support to the gpio-tegra driver,
i.e. driver now could be built as a loadable kernel module.

Dmitry Osipenko (3):
  gpio: tegra: Use debugfs_create_devm_seqfile()
  gpio: tegra: Clean up whitespaces in tegra_gpio_driver
  gpio: tegra: Support building driver as a loadable module

As these three patches clearly make the kernel look better after
than before:

However when we are doing this I would strongly encourage you
to also make a patch implementing remove() so you can insmod
rmmod the module at runtime.

The remove() is optional for drivers, it doesn't prevent the rmmod.
