Message-Id: <20210203195832.2950605-1-mario.limonciello@dell.com>
Date: Wed, 3 Feb 2021 13:58:32 -0600
From: Mario Limonciello <mario.limonciello@...l.com>
To: Hans De Goede <hdegoede@...hat.com>,

Subject: [PATCH v2] platform/x86: Move all dell drivers to their own subdirectory
A user without a Dell system doesn't need to pick any of these
drivers.
Users with a Dell system can enable this submenu and all drivers
behind it will be enabled.
Suggested-by: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>
Signed-off-by: Mario Limonciello <mario.limonciello@...l.com>
---
Changes from v1->v2:
- Rename menu per Andy's suggestion
- Move if/endif for menu into subdirectory
- Set default for menu to "n" but individual modules to "m"
Should be same defaults as previous, but allow an "easy" switch
