Also, local symbols are staticized. Fix the following sparse warnings: drivers/tty/serial/serial-tegra.c:1209:27: warning: Using plain integer as NULL pointer drivers/tty/serial/serial-tegra.c:1240:29: warning: symbol 'tegra20_uart_chip_data' was not declared. Should it be static? drivers/tty/serial/serial-tegra.c:1246:29: warning: symbol 'tegra30_uart_chip_data' was not declared. Should it be static?
