4.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Maxime Chevallier <maxime.chevallier@smile.fr>
commit 5a866ec0014b2baa4ecbb1eaa19c835482829d08 upstream.
When waiting for transfer completion, a3700_spi_wait_completion returns a boolean indicating if a timeout occurred.
The function was returning 'true' everytime, failing to detect any timeout.
This patch makes it return 'false' when a timeout is reached.
