[PATCH v3] platform/x86/amd/hsmp: switch to use device_add_groups()

[Greg Kroah-Hartman]

devm_device_add_groups() is being removed from the kernel, so move the
hsmp driver to use device_add_groups() instead.  The logic is identical,
when the device is removed the driver core will properly clean up and
remove the groups, and the memory used by the attribute groups will be
freed because it was created with dev_* calls, so this is functionally
identical overall.

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

Note it 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
