From 2978a505aaa981b279ef359f74ba93d25098e0a0 Mon Sep 17 00:00:00 2001 From: Helen Fornazier Date: Wed, 6 Mar 2019 17:42:38 -0500 Subject: [PATCH] media: vimc: stream: fix thread state before sleep The state TASK_UNINTERRUPTIBLE should be set just before schedule_timeout() call, so it knows the sleep mode it should enter. There is no point in setting TASK_UNINTERRUPTIBLE at the initialization of the thread as schedule_timeout() will set the state back to TASK_RUNNING. This fixes a warning in __might_sleep() call, as it's expecting the task to be in TASK_RUNNING state just before changing the state to a sleeping state.
