spi: a3700: Return correct value on timeout detection
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. Signed-off-by: Maxime Chevallier <maxime.chevallier@smile.fr> Signed-off-by: Mark Brown <broonie@kernel.org> Cc: stable@vger.kernel.org
