Subject: [PATCH linux-next 2/4] tty/serial: at91: fix some macro definitions to fit coding style
This patch updates macro definitions in atmel_serial.h to fit the
80 column rule.
Please note that some deprecated comments such as "[AT91SAM9261 only]"
are removed as the corresponding bits also exist in some later chips.
The patch also fix macro definitions in atmel_serial.c to replace
(port,v) by (port, v).
