From: Philippe Schenker Date: Tue, 7 May 2019 14:36:14 +0000 (+0200) Subject: iio: stmpe-adc: Use wait_for_completion_timeout X-Git-Tag: v5.3-rc1~126^2~470^2~7 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=e813dde6f83343012239a44e433eacc22de1079c;p=linux-2.6-block.git iio: stmpe-adc: Use wait_for_completion_timeout Use wait_for_completion_timeout instead of wait_for_completion_interuptible_timeout. The interruptible variant gets constantly interrupted if a user program is compiled with the -pg option. The killable variant was not used due to the fact that a second program, reading on this device, that gets killed is then also killing that wait.
