 STOP! It looks like you want to suppress some lint errors:
 - Have you tried identifing the offending patch?
   Ask the author for a fix and/or revert the patch.
 - It is preferred to add suppressions in the code instead of
   sweeping it under the rug here. See:

Done.

I don't understand these suppressions and the reasons why they may be necessary
in this case. Please ask one of chrome/android/java/res/OWNERS to take another
look at it. I can rubberstamp after that.

twellington took a look and commented previously. It's necessary because the
TableLayout only has one child row and is populated dynamically.

Thank you for explanation, I did not notice.
