  Kernel module "ideapad_laptop" kills WiFi on Lenovo Yoga C930 (18.10

Status in linux package in Ubuntu:

Bug description:
  I've just made a fresh install of Ubuntu 18.10 Cosmic on a brand-new
  Lenovo Yoga C930. The installation went super-fast, but in the end
  there was no WiFi.

  $ uname -a
  Linux roma 4.18.0-10-generic #11-Ubuntu SMP Thu Oct 11 15:13:55 UTC 2018 
x86_64 x86_64 x86_64 GNU/Linux

  Turns out that I had to blacklist the kernel module "ideapad_laptop"
  to make everything work just fine. Several sources report this online,
  e.g. [¹]. I've been told on IRC #ubuntu that there's an alternative
  approach to get this fixed w/o blacklisting, see [²].

  Other Lenovo Yoga models seem to be affected likewise, e.g. the C920.
  According to user jeremy31 on IRC this issue has existed for a few
  years, and a user ryuo wrote the code he provides as a fix on GitHub.

  Can this be fixed upstream to make a fresh installation "just work"
  out of the box?
