Subject: serial: 8250: convert drivers to use up_to_u8250p()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=013e3586d84bfe9f6b4b44eecdc3842978644d78;p=openwrt%2Fstaging%2Fblogic.git

serial: 8250: convert drivers to use up_to_u8250p()

up_to_u8250p() casts struct uart_port * to struct uart_8250_port *. Update code
to use it instead of open coded variant.
