| * staging: imx-drm: Fix probe failureFabio Estevam2013-09-261-8/+3

[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 openMalcolm Priestley2013-09-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | Don't allow entry to iwctl_siwencodeext if device not open.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

In device_create_release, the dev is kfreed. However, device_shutdown attempts to use the dev pointer again after put_device by referring to dev->parent. Copy the parent pointer instead to avoid this condition. This bug was found on Chromium OS's chromeos-3.8, which is based on v3.8.11. See bug report : https://code.google.com/p/chromium/issues/detail?id=297842 This can easily be reproduced when shutting down with hidraw devices that report battery condition. Two examples are the HP Bluetooth Mouse X4000b and the Apple Magic Mouse. For example, with the magic mouse : The dev in question is "hidraw0" dev->parent is "magicmouse" In the course of the shutdown for this device, the input event cleanup calls a put on hidraw0, decrementing its reference count. When we finally get to put_device(dev) in device_shutdown, kobject_cleanup is called and device_create_release does kfree(dev). dev->parent is no longer valid, and we may crash in put_device(dev->parent).

Clocks above that level tend to be unstable and will require additional driver tweaks in order to work properly. This patch implemented the helper function to fetch the max clocks from the dependency tables. The following patches implement the per-asic clock filtering.

Note that after resume the bios might or might not have enabled pipe A already. We have a bit of magic to make sure that on resume we set up a decent mode for pipe A, but I fear if I just smash pipe A to always on we'd enable it in a bogus state and hang the hw. Hence the readback. v2: Clarify the logic a bit as suggested by Chris. Also amend the commit message to clarify why we don't unconditionally enable the pipe.

This worked out nicely since the input modes used by both the load detect code and reported in the ->get_modes callbacks all have no flags set, and we also don't fill out any of them in the ->get_config callback. This changed with the additional sanitation done with commit 2960bc9cceecb5d556ce1c07656a6609e2f7e8b0 Author: Imre Deak <imre.deak@intel.com> Date: Tue Jul 30 13:36:32 2013 +0300 drm/i915: make user mode sync polarity setting explicit sinc now the "no flags at all" state wouldn't fit through core code any more. So fix this up again by explicitly clearing the flags in the ->compute_config callback. Aside: We have zero checking in place to make sure that the requested mode is indeed the right input mode we want for the selected TV mode. So we'll happily fall over if userspace tries to pull us. But that's definitely work for a different patch series. So just add a FIXME comment for now.

The first pass finds the length, and the second pass emits the right portion of the string into the accumulation buffer. Unfortunately we use the same va_list for both passes, resulting in the second pass reading garbage off the end of the argument list. As the two passes are only used for boundaries between read() calls, the corruption is only rarely seen.
