Rakesh Babu Saladi says:

====================
RVU Debugfs updates.

Patch 1: Few minor changes such as spelling mistakes, deleting unwanted
characters, etc.
Patch 2: Add debugfs dump for lmtst map table
Patch 3: Add channel and channel mask in debugfs.

Changes made from v2 to v3:
1. In patch 1 moved few lines and submitted those changes as a
different patch to net branch
2. Patch 2 is left unchanged.
3. Patch 3 is left unchanged.
