Subject: serial: mux: Convert to uart_console_device instead of open-coded
X-Git-Tag: v4.4-rc1~126^2~90
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=57e7e2a64a49961d2810a6f4f0e1ca2699338ec2;p=platform%2Fkernel%2Flinux-exynos.git

serial: mux: Convert to uart_console_device instead of open-coded

The implementation of mux_console_device() is very similar to
uart_console_device(). Setting .data field in mux_console then we can
convert to use uart_console_device().
