Since commit b5dc0d10 (drm/imx: kill firstopen callback) the following probe
failure is seen:
[drm] Supports vblank timestamp caching Rev 1 (10.10.2010).
[drm] No driver support for vblank timestamp query.
[drm] Initialized imx-drm 1.0.0 20120507 on minor 0
imx-ldb ldb.10: adding encoder failed with -16

imx-ipuv3-crtc imx-ipuv3-crtc.2: adding crtc failed with -16.
imx-ipuv3-crtc: probe of imx-ipuv3-crtc.2 failed with error -16
imx-ipuv3-crtc imx-ipuv3-crtc.3: adding crtc failed with -16.
imx-ipuv3-crtc: probe of imx-ipuv3-crtc.3 failed with error -16
The reason for the probe failure is that now 'imxdrm->references' is incremented
early in imx_drm_driver_load(), so the following checks in imx_drm_add_crtc()
and imx_drm_add_encoder():
if (imxdrm->references) {
ret = -EBUSY;
goto err_busy;
}
,will always fail.
Instead of manually keeping the references in the imx-drm driver, let's use
drm->open_count.
After this patch, lvds panel is functional on a mx6qsabrelite board.

The vt6656 is prone to resetting on the usb bus.
It seems there is a race condition and wpa supplicant is
trying to open the device via iw_handlers before its actually
closed at a stage that the buffers are being removed.
The device is longer considered open when the
buffers are being removed. So move ~DEVICE_FLAGS_OPENED
flag to before freeing the device buffers.

There seems to be race condition that the device is ndo_start_xmit
at a point where the device is closing and apTD is NULL resulting
in dead lock.
Add a NULL check to apTD and return NULL to calling functions.
This is more likely on 64 bit systems.

places. The first call resides outside an #ifdef RTL8192U guard, and since
RTL8192U is defined this call can be removed. At the other site this function
is called, there is no check on its return value. Since cmpk_message_handle_tx()
does not do anything else other than returning true, it can be safely removed.

The transfer scheduler in the dwc2 driver is pretty basic, not to
mention buggy. It works fairly well with just a couple of devices
plugged in, but if you add, say, multiple devices with periodic
endpoints, the scheduler breaks down and can't even enumerate all
the devices.
To improve this, import the "microframe scheduler" patch from the
driver in the downstream Raspberry Pi kernel, which is based on
the Synopsys vendor driver. The original patch came from Denx
(http://git.denx.de/?p=linux-denx.git) and was commited to the
raspberrypi.org git tree by "popcornmix" (Dom Cobley).
I have added a driver parameter for this, enabled by default, in
case anyone has problems with it and needs to disable it. I don't
think we should add a DT binding for that, though, since I plan
to remove the option once any bugs are fixed.

getaddrinfo() leaves the order of the returned addrinfo structs
unspecified. On systems with bindv6only disabled (this is the default),
PF_INET6 sockets bind to IPv4, too. Thus, IPv6 support in usbipd was
broken when getaddrinfo returned first IPv4 and then IPv6 addrinfos, as
the IPv6 bind failed with EADDRINUSE.
This patch uses seperate sockets for IPv4 and IPv6 and sets IPV6_V6ONLY
on all IPv6 sockets. Two command line arguments, -4 and -6 were added to
manually select the socket family.
