+awhalley@ (Security TPM) for M69 merge review.

Good to approve for 69 tomorrow just to give a bit more time in Canary

The NextAction date has arrived: 2018-08-08

How is the change looking in canary?

+jkummerow@ (CL reviewer), PTAL comment #18 and #21. Thank you.

This is the same situation as  crbug.com/866282#c24 . M69 is not affected. Sheriffbot should learn to look at actual branches for DEPS'ed in projects, not just commit dates.

This bug has been closed for more than 14 weeks. Removing security view restrictions.
