From 70dc6daff090afaab588e800fca3db59bfac694e Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 7 Jan 2016 13:03:08 +0300 Subject: [PATCH] regulator: core: remove some dead code Originally queue_delayed_work() used to negative error codes or 0 and 1 on success depending if the work was queued or not. It caused a lot of bugs where people treated all non-zero returns as failures so we changed it to return bool instead in d4283e937861 ('workqueue: make queueing functions return bool'). Now it never returns failure. Checking for negative values causes a static checker warning since it is impossible based on the bool type.
