[PATCH 00/07] Remove and replace all un-needed DPRINT and printk
This patch set removes all un-needed DPRINT and printk calls and replaces the remaining ones with the correct pr_, dev_ and netdev_ calls from hv_vmbus, hv_netvsc, hv_timesource and hv_utils. Several DPRINTS are remaining that will be cleaned up in my next set of patches. They deal with printing out certain debugging that will be implemented slightly differently. The remaining hv_storvsc and hv_blkvsc will get the same treatment in a different set of patches. Regards, Hank Janssen <hjanssen at microsoft.com>
Remove all un-needed DPRINT calls from hv_vmbus. Several
are remaining that will be cleaned up in my next set of patches.
They deal with printing out the ringbuffer debugging which is
going to be implemented slightly differently.
This patch deals with hv_vmbus only.

1.6.0.2
Replace all remaining DPRINT calls (excluding the ringbuffer debug
which is going to be done in a next set of patches) with their
native pr_ calls. And also changed some of the printouts to be more
useful.

[PATCH 05/07] replace DPRINT with native primitives in hv_netvsc
Replace all remaining DPRINT calls with their native dev_ and
netvsc_ calls. And also change some of the verbiage to be more useful.
rndis_filter has a few remaining DPRINT calls in it that will be removed
in a future patch because the debug will be implemented differently.
