From 0c90f649d2f5b9c6c585cab293a4e40172ddaa73 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 3 Nov 2019 15:01:42 +0100 Subject: [PATCH] media: vivid: add vivid_create_queue() helper Refactor some of the vivid_create_instance code by using a new vivid_create_queue() helper function. Also add some sanity checks for the node_types vs input/output_types module options. This patch resolves these two smatch parse errors: drivers/media/platform/vivid/vivid-core.c:1679 vivid_create_instance() parse error: OOM: 3002600Kb sm_state_count = 6160113 drivers/media/platform/vivid/vivid-core.c: drivers/media/platform/vivid/vivid-core.c:1679 vivid_create_instance() parse error: __split_smt: function too hairy.
