Subject: mxser: make use of UART_LCR_WLEN() + tty_get_char_size()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e7d6f84c9b5aaddf119b11799fd13411d33f13dd;p=linux.git

mxser: make use of UART_LCR_WLEN() + tty_get_char_size()

Having a generic UART_LCR_WLEN() macro and the tty_get_char_size()
helper, we can remove all those repeated switch-cases in drivers.
