This series supports NCSI debugging infrastructure by adding several
debugfs files. It was inspired by the reported issues: No available
package and channel are probed successfully. Obviously, we don't
have a debugging infrastructure for NCSI stack yet.
The first 3 patches, fixing some issues, aren't relevant to the
subject. I included them because I expect they can be merged beofre
the code for debugging infrastructure. PATCH[4,5,6/8] adds debugfs
directories and files to support the debugging infrastructure for
several purposes: presenting the NCSI topology; statistics on sent
and received NCSI packets; generate NCSI command packet manually.
PATCH[7,8/8] fixes two issues found from the debugging functionality.
Changelog
