From 2b177f2849d23061508bb13594cc1bff1ccb46c9 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 5 Mar 2019 03:36:20 -0500 Subject: media: vimc: use new release op Use the new v4l2_subdev_internal_ops release op to free the subdev memory only when the last user closed the file handle. Move v4l2_device_unregister_subdev() to the end of the vimc_ent_sd_unregister() function since now the unregister_subdev() call may free the vimc_ent_device struct which is used after the unregister_subdev() call. So this now has to be done last.
