[PATCH v3 13/14] serial: 8250_tegra: Switch to use uart_read_port_properties()
From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

Subsystem:
8250/16?50 (and clone uarts) serial driver, the rest, tty layer and serial drivers · Maintainers:
Greg Kroah-Hartman, Linus Torvalds, Jiri Slaby
Since we have now a common helper to read port properties use it instead of sparse home grown solution. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> --- drivers/tty/serial/8250/8250_tegra.c | 26 +++++++++----------------- 1 file changed, 9 insertions(+), 17 deletions(-)
