This is workaround / partial fix. rtl2832u_power_ctrl() and rtl2832u_frontend_attach() needs to be go through carefully and fix properly. There is clearly some logical errors when handling power-management ang GPIOs... Signed-off-by:

Stream did not start anymore after stream was stopped once. Following error can be seen, xhci_hcd WARN Set TR Deq Ptr cmd failed due to incorrect slot or ep state. usb_clear_halt for streaming endpoint helps. Signed-off-by:

I didn't found easy way to handle register dump only when needed so remove it totally. It is quite useless and trivial function, every developer could write new one in few minutes when needed. Signed-off-by:

Changing cached frequency during init is something no-no. Make it behave a little bit better. After that device could survive from suspend/resume when streaming is ongoing. Signed-off-by:

ite_dev::rdev is currently initialised in ite_probe() after rc_register_device() returns. If a newly registered device is opened quickly enough, we may enable interrupts and try to use ite_dev::rdev before it has been initialised. Move it up to the earliest point we can, right after calling rc_allocate_device(). Reported-and-tested-by:

[media] gspca_pac7302: avoid duplicate calls of the image quality adjustment functions on capturing start There is no need to call the image quality adjustment functions in sd_start. The gspca main driver calls v4l2_ctrl_handler_setup in gspca_init_transfer, which already applies all image control values. Signed-off-by:

1) We always re-create the input-urb on resume, so we must also always destroy it on suspend to avoid leaking it 2) If we're going to do an init_transfer, then that will destroy the urb before starting the stream (nop if there is none), and (re-)create it once the stream is started. So there is little use in creating it, if we're going to do an init_transfer immediately afterward Signed-off-by:

gspca_main: init_transfer does not do anything between calling sd_start (which starts the workqueue) and releasing the usb_lock, so this synchronization is a nop, remove it. Signed-off-by:

In commit a3d6e8cc gspca_dev->dev is set to NULL on disconnect, before calling stop0. The plan was to get rid of gspca_dev->present and instead simply check for gspca_dev->dev everywhere where we were checking for present. This should be race free since all users of gspca_dev->dev hold the usb_lock, or so I thought. But I was wrong, drivers which use a work-queue + synchronous bulk transfers to get the video data don't hold the usb_lock while doing so, their stop0 callbacks stop the workqueue, so they won't be using gspca_dev->dev anymore after the stop0 call, but they might be dereferincing it before, so we should not set gspca_dev->dev to NULL on disconnect before calling stop0. This also means that the workqueue functions in these drivers cannot use gspca_dev->dev to check if they need to stop because of disconnection, so we will need to keep gspca_dev->present around, and set that to 0 on disconnect, before calling stop0. Unfortunately as part of the plan to remove gspca_dev->present, these workqueues where already moved over to checking for gspca_dev->dev instead of gspca_dev->present as part of commit 254902b0, so this patch also reverts those parts of that commit.

Convert a nonnegative error return code to a negative one, as returned elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by:

This patch changes some signed integers to unsigned because they are not intended for negative values and sparse is making noise about it. Sparse gives eight of these errors: drivers/media/usb/gspca/ov519.c:144:29: error: dubious one-bit signed bitfield Signed-off-by:

changeset 1248c7cb broke html compilation: Documentation/DocBook/v4l2.xml:584: parser error : Entity 'sub-subdev-g-edid' not defined Documentation/DocBook/v4l2.xml:626: parser error : chunk is not well balanced Documentation/DocBook/media_api.xml:74: parser error : Failure to process entity sub-v4l2 Documentation/DocBook/media_api.xml:74: parser error : Entity 'sub-v4l2' not defined I suspect that one file was simply missed at the patch. Yet, keeping it broken is a very bad idea, so we should either remove the broken patch or to remove just the invalid include. Let's take the latter approach. Due to that, a warning is now produced: Error: no ID for constraint linkend: v4l2-subdev-edid. Cc: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by:
