Fix build error with gcc 4.8.2 about WARN_UNUSED_RESULT
For static methods it does not seem to work properly with older gcc.
Indeed the compiler consider the result as not used in this example:
sequence_token_ = BrowserThread::GetBlockingPool()->GetSequenceToken()
"error: ignoring return value of 'static base::SequencedWorkerPool*
content::BrowserThread::GetBlockingPool()', declared with attribute
warn_unused_result [-Werror=unused-result]"
The solution is just to call GetSequenceToken() directly as:
base::SequencedWorkerPool::GetSequenceToken() as it is static.
