3.16.60-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Uwe Kleine-König <u.kleine-koe...@pengutronix.de>
commit 0e254963b6ba4d63ac911e79537fea38dd03dc50 upstream.
Most register accesses in the altera driver honor port->regshift by
using altera_uart_writel(). There are a few accesses however that were
missed when the driver was converted to use port->regshift and some
others were added later in commit 4d9d7d896d77 ("serial: altera_uart:
add earlycon support").
Fixes: 2780ad42f5fe ("tty: serial: altera_uart: Use port->regshift to store bus
shift")
