From: Dave Gordon david.s.gordon@intel.com
commit 30b0da8d556e65ff935a56cd82c05ba0516d3e4a upstream.
We had only DRM_INFO() and DRM_ERROR(), whereas the underlying printk() provides several other useful intermediate levels such as NOTICE and WARNING. So this patch fills out the set by providing both regular and once-only macros for each of the levels INFO, NOTICE, and WARNING, using a common underlying macro that does all the token-pasting.
DRM_ERROR is unchanged, as it's not just a printk wrapper.
