Bug Description
[Impact]
I2C designware fails to get its adapter number, and this may lead to fail to access touchpad through I2C bus.
[ 6.476367] WARNING: CPU: 9 PID: 567 at /build/
[Fix]
The 2 commits from v5.1-rc1 fix this issue.
cd86d1403bb4 i2c: i2c-designware-
77f3381a83c2 i2c: i2c-designware-
[Test]
Verified on Dell machine which had this issue.
[Regression Potential]
Low, the 2 commits make it always use dynamic adapter-numbers which does not make any difference in most cases and in the one case where it does make a difference the behavior change is desirable because the old behavior caused an oops.
