4.13-stable review patch. If anyone has any objections, please let me know.
------------------ From: Maxime Chevallier <[email protected]> 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.
