staging: imx-drm: Fix probe failure

2013-09-25T23:53:40+00:00

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-ldb: probe of ldb.10 failed with error -16
imx-ipuv3 2400000.ipu: IPUv3H probed
imx-ipuv3 2800000.ipu: IPUv3H probed
imx-ipuv3-crtc imx-ipuv3-crtc.0: adding crtc failed with -16.
imx-ipuv3-crtc: probe of imx-ipuv3-crtc.0 failed with error -16
imx-ipuv3-crtc imx-ipuv3-crtc.1: adding crtc failed with -16.
imx-ipuv3-crtc: probe of imx-ipuv3-crtc.1 failed with error -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.

staging: vt6656: [BUG] iwctl_siwencodeext return if device not open

2013-09-25T23:53:40+00:00

Don't allow entry to iwctl_siwencodeext if device not open.

This fixes a race condition where wpa supplicant/network manager
enters the function when the device is already closed.

staging: vt6656: [BUG] main_usb.c oops on device_close move flag earlier.

2013-09-25T23:53:40+00:00

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.

staging: vt6656: rxtx.c [BUG] s_vGetFreeContext dead lock on null apTD.

2013-09-25T23:53:39+00:00

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.
