Merge branch 'for-davem' of git://gitorious.org/linux-can/linux-can-next
Marc Kleine-Budde says:
====================
this is a pull-request for net-next/master. It consists of 4 patches by
Jingoo Han, which remove the unnecessary platform_set_drvdata() and a
patch by Laurent Navet converting the grcan driver to use
devm_ioremap_resource().
