[Impact]
[ELAN900C:00 04F3:2844] doesn't work

[Fix]
It works under kernel v4.19, so after bisect the kernel and got the first bad commit
   e50d95e2ad12 pinctrl: cannonlake: Fix HOSTSW_OWN register offset of H variant

[Test]
Verified on the DELL machine, the touchscreen works well.

[Regression Potential]
Low, the 2 commits are all
   Fixes: a663ccf0fea1 ("pinctrl: intel: Add Intel Cannon Lake PCH-H pin controller support")
Should be safe to be included.

Andy Shevchenko (1):
  pinctrl: cannonlake: Fix community ordering for H variant
