Subject: [PATCH v2] platform/x86: Move Lenovo files into lenovo subdir
Create lenovo subdirectory for holding Lenovo specific drivers.
Signed-off-by: Mark Pearson <mpearson-lenovo@...ebb.ca>
---
Changes in v2:
- Rebased to Linus's latest as requested
- Updated documentation reference
- Updated MAINTAINER file
- Removed X86_PLATFORM_DRIVERS_LENOVO as I was worried about
maintaining backwards compatibility for the distros.
- Removed 2nd patch in series splitting out hkeys. That will be for
the future
