Subject: [PATCH 2/6] Xilinxfb: Replace calls to printk with dev_dbg, dev_err,
	etc.

From: Grant Likely <grant.likely@...retlab.ca>

The dev_dbg, dev_err, etc functions provide more context that plain
vanilla printk which is useful for debugging.  Where appropriate,
change printk calls to the appropriate dev_*() call.
