Subject: [PATCH v2 5/9] platform/x86: asus-wmi: store a min default for ppt options
Laptops with any of the ppt or nv tunables default to the minimum setting
on boot so we can safely assume a stored value is correct.
This patch adds storing of those values in the local struct, and enables
reading of those values back. To prevent creating a series of byte holes
in the struct the "<name>_available" bool is removed and
`asus_sysfs_is_visible()` uses the `ASUS_WMI_DEVID_<name>` directly.
