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 <[email protected]>

---
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

Thank you for your patch, I've applied this patch to my review-hans
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans
There was one small issue with the patch, all the "default m" lines
which you added were indented with 4 spaces instead of a tab, I've
fixed this up locally.
The patch will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.
Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.
Regards,
Hans
