Media drivers that use the videobuf2 framework have to give back to vb2 all the buffers that received from vb2 using its .buf_queue callback. But the exynos-gsc driver isn't doing a proper cleanup so vb2 complains that the number of buffers enqueued and received are not balanced: WARNING: CPU: 2 PID: 660 at drivers/media/v4l2-core/videobuf2-core.c:1654 __vb2_queue_cancel+0xec/0x150 [videobuf2_core] Modules linked in: mwifiex_sdio mwifiex uvcvideo exynos_gsc videobuf2_vmalloc s5p_mfc s5p_jpeg CPU: 2 PID: 660 Comm: lt-gst-validate Not tainted 4.8.0 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) [<c010e24c>] (unwind_backtrace) from [<c010af30>] (show_stack+0x10/0x14) [<c010af30>] (show_stack) from [<c03291a4>] (dump_stack+0x88/0x9c) [<c03291a4>] (dump_stack) from [<c011a858>] (__warn+0xe8/0x100) [<c011a858>] (__warn) from [<c011a920>] (warn_slowpath_null+0x20/0x28) [<c011a920>] (warn_slowpath_null) from [<bf0b6ed0>] (__vb2_queue_cancel+0xec/0x150 [videobuf2_core]) [<bf0b6ed0>] (__vb2_queue_cancel [videobuf2_core]) from [<bf0b7464>] (vb2_core_streamoff+0x34/0x9c [videobuf2_core]) [<bf0b7464>] (vb2_core_streamoff [videobuf2_core]) from [<bf11b9e8>] (v4l2_m2m_streamoff+0x2c/0xe4 [v4l2_mem2mem]) [<bf11b9e8>] (v4l2_m2m_streamoff [v4l2_mem2mem]) from [<bf01b84c>] (__video_do_ioctl+0x298/0x30c [videodev]) [<bf01b84c>] (__video_do_ioctl [videodev]) from [<bf01b234>] (video_usercopy+0x174/0x4e8 [videodev]) [<bf01b234>] (video_usercopy [videodev]) from [<bf0165c8>] (v4l2_ioctl+0xc4/0xd8 [videodev]) [<bf0165c8>] (v4l2_ioctl [videodev]) from [<c01f291c>] (do_vfs_ioctl+0x9c/0x8f4) [<c01f291c>] (do_vfs_ioctl) from [<c01f31a8>] (SyS_ioctl+0x34/0x5c) [<c01f31a8>] (SyS_ioctl) from [<c01078c0>] (ret_fast_syscall+0x0/0x3c) Fix this by passing back to vb2 all the received buffers that were not processed.
