[PATCH] regulator: core: Print at debug level on debugfs creation failure

[Stephen Boyd]

Failure to create a debugfs node is not an error, but we print a
warning upon failure to create the node. Downgrade this to a
debug printk so that we're quiet here. This allows multiple
drivers to request a CPU's regulator so that CPUfreq and AVSish
drivers can coexist.

The downside of this approach is that whoever gets to debugfs first
the others who come later to not have any debugfs attributes associated
with them.
