This namespace is not used by this file and its declaration is removed in a separate CL from utils/Log.h, which is the only place it is defined, so we must remove this extraneous line. Also, since that separate CL is deprecating utils/Log.h in favor of log/log.h, we make the switch to the new header. Test: Build Change-Id: Iac4bc8faffbd2d68dc4ccccaf569db0c5a13a7bc
