Anton Sviridenko 6e4c8480bd [media] solo6x10: release vb2 buffers in solo_stop_streaming() ... Fixes warning that appears in dmesg after closing V4L2 userspace application that plays video from the display device (first device from V4L2 device nodes provided by solo, usually /dev/video0 when no other V4L2 devices are present). Encoder device nodes are not affected. Can be reproduced by starting and closing ffplay -f video4linux2 /dev/video0 [ 8130.281251] ------------[ cut here ]------------ [ 8130.281256] WARNING: CPU: 1 PID: 20414 at drivers/media/v4l2-core/videobuf2-core.c:1651 __vb2_queue_cancel+0x14b/0x230 [ 8130.281257] Modules linked in: ipt_MASQUERADE nf_nat_masquerade_ipv4 iptable_nat solo6x10 x86_pkg_temp_thermal vboxpci(O) vboxnetadp(O) vboxnetflt(O) vboxdrv(O) [ 8130.281264] CPU: 1 PID: 20414 Comm: ffplay Tainted: G O 4.10.0-gentoo #1 [ 8130.281264] Hardware name: ASUS All Series/B85M-E, BIOS 2301 03/30/2015 [ 8130.281265] Call Trace: [ 8130.281267] dump_stack+0x4f/0x72 [ 8130.281270] __warn+0xc7/0xf0 [ 8130.281271] warn_slowpath_null+0x18/0x20 [ 8130.281272] __vb2_queue_cancel+0x14b/0x230 [ 8130.281273] vb2_core_streamoff+0x23/0x90 [ 8130.281275] vb2_streamoff+0x24/0x50 [ 8130.281276] vb2_ioctl_streamoff+0x3d/0x50 [ 8130.281278] v4l_streamoff+0x15/0x20 [ 8130.281279] __video_do_ioctl+0x25e/0x2f0 [ 8130.281280] video_usercopy+0x279/0x520 [ 8130.281282] ? v4l_enum_fmt+0x1330/0x1330 [ 8130.281285] ? unmap_region+0xdf/0x110 [ 8130.281285] video_ioctl2+0x10/0x20 [ 8130.281286] v4l2_ioctl+0xce/0xe0 [ 8130.281289] do_vfs_ioctl+0x8b/0x5b0 [ 8130.281290] ? __fget+0x72/0xa0 [ 8130.281291] SyS_ioctl+0x74/0x80 [ 8130.281294] entry_SYSCALL_64_fastpath+0x13/0x94 [ 8130.281295] RIP: 0033:0x7ff86fee6b27 [ 8130.281296] RSP: 002b:00007ffe467f6a08 EFLAGS: 00000246 ORIG_RAX: 0000000000000010 [ 8130.281297] RAX: ffffffffffffffda RBX: 00000000d1a4d788 RCX: 00007ff86fee6b27 [ 8130.281297] RDX: 00007ffe467f6a14 RSI: 0000000040045613 RDI: 0000000000000006 [ 8130.281298] RBP: 000000000373f8d0 R08: 00000000ffffffff R09: 00007ff860001140 [ 8130.281298] R10: 0000000000000243 R11: 0000000000000246 R12: 0000000000000000 [ 8130.281299] R13: 00000000000000a0 R14: 00007ffe467f6530 R15: 0000000001f32228 [ 8130.281300] ---[ end trace 00695dc96be646e7 ]--- Signed-off-by: Anton Sviridenko <anton@corp.bluecherry.net> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>		2017-03-22 11:57:31 -03:00
