From: Archit Taneja Date: Fri, 20 Jul 2012 13:00:50 +0000 (+0530) Subject: OMAPDRM: Remove manager->device references X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=23e2aa644f39fbc8121f49dd50ce85590cc4e4b7;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git OMAPDRM: Remove manager->device references With the introduction of output entities, managers will now connect to outputs. Use the helper op for managers named get_device. This will abstract away the information on how to get the device from an overlay manager. Using the helper function will reduce the number of pointer dereferences a user of OMAPDSS needs to do and reduce risk of a NULL dereference.
