After upgrading from Linux 5.4.68 to Linux 5.4.69, the touchscreen of my Huawei Matebook 12 doesn't work anymore. The same issue happens with Linux >= 5.8.13.
I've compiled Linux from git to verify if it was fixed, but it doesn't help. But when reverting the commit 21653a4181ff292480599dad996a2b759ccf050f the touchscreen works fine again.
For reference my Arch Linux bug report:
- CPU Intel Core m3-6Y30
- GPU Intel Graphics 515
Sorry about the regression. A patch fixing this has been posted upstream, see:
