[PATCH 02/29] ARM: shmobile: sh7372: Use macros to declare SCIF devices

Simon Horman horms+renesas at verge.net.au
Tue Dec 24 09:15:46 EST 2013


From: Laurent Pinchart <laurent.pinchart+renesas at ideasonboard.com>

Replace copy-n-paste SCIF platform data and device declaration with a
macro. This reduces the amount of code and improves readability.
