====================
tun: debug messages cleanup
While testing ethtool output for "strange" devices, I noticed confusing and
obviously incorrect message level information for a tun device and sent
a quick fix. The result of the upstream discussion was that tun driver
would rather deserve a more complex cleanup of the way it handles debug
messages.
The main problem is that all debugging statements and setting of message
level are controlled by TUN_DEBUG macro which is only defined if one edits
the source and rebuilds the module, otherwise all DBG1() and tun_debug()
statements do nothing.
This series drops the TUN_DEBUG switch and replaces custom tun_debug()
macro with standard netif_info() so that message level (mask) set and
displayed using ethtool works as expected. Some debugging messages are
dropped as they only notify about entering a function which can be done
easily using ftrace or kprobe.
Patch 1 is a trivial fix for compilation warning with W=1.
