Subject: [PATCH] staging: sm7xx: code improvements and cleanup
This patch implements some code improvements and cleanup.
New code uses dynamic debug support. Old debug calls updated/tested to
use this API.
Cleanup on obsolete references, internal versions and some
comments. Dead code removal.
Patch tested with SM712.
Changes:
- Code improvements and cleanup
- Use dynamic debug support
- Remove out-of-date comments/references
- Remove dead code
