From a4ac45aff8d38c64104aec21c6529747d94ae75a Mon Sep 17 00:00:00 2001 From: Sean Young Date: Tue, 14 Sep 2021 16:57:46 +0200 Subject: [PATCH] media: ir_toy: prevent device from hanging during transmit [ Upstream commit 4114978dcd24e72415276bba60ff4ff355970bbc ] If the IR Toy is receiving IR while a transmit is done, it may end up hanging. We can prevent this from happening by re-entering sample mode just before issuing the transmit command.
