The code to enable LPM support by default on mobile chipsets was merged
in the 4.16 kernel, so 4.14 (and older) don't need these blacklist patches
since they don't enable LPM by default (the user needs to write to a sysfs
attribute to enable it).

So it is fine to leave this patch out of 4.14.z and older.

Regards,

Hans
