2014-02-04[media] v4l2-dv-timings: fix GTF calculationMartin Bugge
Round off image width to nearest 8 (GTF_CELL_GRAN) A source sending a GTF (Generalized Timing Formula) format have no means of signalling image width. The assumed aspect ratio may result in an odd image width but according to the standard image width should be in multiple of 8.

2014-02-04[media] mxl111sf: Fix unintentional garbage stack readDave Jones
mxl111sf_read_reg takes an address of a variable to write to as an argument. drivers/media/usb/dvb-usb-v2/mxl111sf-gpio.c:mxl111sf_config_pin_mux_modes passes several uninitialized stack variables to this routine, expecting them to be filled in. In the event that something unexpected happens when reading from the chip, we end up doing a pr_debug of the value passed in, revealing whatever garbage happened to be on the stack. Change the pr_debug to match what happens in the 'success' case, where we assign buf[1] to *data.

2014-02-04[media] Revert "[media] videobuf_vm_{open,close} race fixes"Hans Verkuil
This reverts commit a242f426108c284049a69710f871cc9f11b13e61. That commit actually caused deadlocks, rather then fixing them. If ext_lock is set to NULL (otherwise videobuf_queue_lock doesn't do anything), then you get this deadlock: The driver's mmap function calls videobuf_mmap_mapper which calls videobuf_queue_lock on q. videobuf_mmap_mapper calls __videobuf_mmap_mapper, __videobuf_mmap_mapper calls videobuf_vm_open and videobuf_vm_open calls videobuf_queue_lock on q (introduced by above patch): deadlocked. This affects drivers using dma-contig and dma-vmalloc. Only dma-sg is not affected since it doesn't call videobuf_vm_open from __videobuf_mmap_mapper. Most drivers these days have a non-NULL ext_lock. Those that still use NULL there are all fairly obscure drivers, which is why this hasn't been seen earlier. Since everything worked perfectly fine for many years I prefer to just revert this patch rather than trying to fix it. videobuf is quite fragile and I rather not touch it too much. Work is (slowly) progressing to move everything over to vb2 or at the very least use non-NULL ext_lock in videobuf.

2014-02-03ACPI / hotplug / PCI: Fix bridge removal race vs dock eventsRafael J. Wysocki
If a PCI bridge with an ACPIPHP context attached is removed via sysfs, the code path executed as a result is the following: pci_stop_and_remove_bus_device_locked pci_remove_bus pcibios_remove_bus acpi_pci_remove_bus acpiphp_remove_slots cleanup_bridge unregister_hotplug_dock_device (drops dock references to the bridge) put_bridge free_bridge acpiphp_put_context (for each child, under context lock) kfree (context) Now, if a dock event affecting one of the bridge's child devices occurs (roughly at the same time), it will lead to the following code path: acpi_dock_deferred_cb dock_notify handle_eject_request hot_remove_dock_devices dock_hotplug_event hotplug_event (dereferences context) That may lead to a kernel crash in hotplug_event() if it is executed after the last kfree() in the bridge removal code path. To prevent that from happening, add a wrapper around hotplug_event() called dock_event() and point the .handler pointer in acpiphp_dock_ops to it. Make that wrapper retrieve the device's ACPIPHP context using acpiphp_get_context() (instead of taking it from the data argument) under acpiphp_context_lock and check if the parent bridge's is_going_away flag is set. If that flag is set, it will return immediately and if it is not set it will grab a reference to the device's parent bridge before executing hotplug_event(). Then, in the above scenario, the reference to the parent bridge held by dock_event() will prevent free_bridge() from being executed for it until hotplug_event() returns. Signed-off-by: Rafael J.

2014-02-03ACPI / hotplug / PCI: Fix bridge removal race in handle_hotplug_event()Rafael J. Wysocki
If a PCI bridge with an ACPIPHP context attached is removed via sysfs, the code path executed as a result is the following: pci_stop_and_remove_bus_device_locked pci_remove_bus pcibios_remove_bus acpi_pci_remove_bus acpiphp_remove_slots cleanup_bridge put_bridge free_bridge acpiphp_put_context (for each child, under context lock) kfree (child context) Now, if a hotplug notify is dispatched for one of the bridge's children and the timing is such that handle_hotplug_event() for that notify is executed while free_bridge() above is running, the get_bridge(context->func.parent) in handle_hotplug_event() will not really help, because it is too late to prevent the bridge from going away and the child's context may be freed before hotplug_event_work() scheduled from handle_hotplug_event() dereferences the pointer to it passed via the data argument. That will cause a kernel crash to happpen in hotplug_event_work(). To prevent that from happening, make handle_hotplug_event() check the is_going_away flag of the function's parent bridge (under acpiphp_context_lock) and bail out if it's set. Also, make cleanup_bridge() set the bridge's is_going_away flag under acpiphp_context_lock so that it cannot be changed between the check and the subsequent get_bridge(context->func.parent) in handle_hotplug_event(). Then, in the above scenario, handle_hotplug_event() will notice that context->func.parent->is_going_away is already set and it will exit immediately preventing the crash from happening.

2014-02-03ACPI / hotplug / PCI: Move PCI rescan-remove locking to hotplug_event()Rafael J. Wysocki
Commit 9217a984671e (ACPI / hotplug / PCI: Use global PCI rescan-remove locking) modified ACPIPHP to protect its PCI device removal and addition code paths from races against sysfs-driven rescan and remove operations with the help of PCI rescan-remove locking. However, it overlooked the fact that hotplug_event_work() is not the only caller of hotplug_event() which may also be called by dock_hotplug_event() and that code path is missing the PCI rescan-remove locking. This means that, although the PCI rescan-remove lock is held as appropriate during the handling of events originating from handle_hotplug_event(), the ACPIPHP's operations resulting from dock events may still suffer the race conditions that commit 9217a984671e was supposed to eliminate. To address that problem, move the PCI rescan-remove locking from hotplug_event_work() to hotplug_event() so that it is used regardless of the way that function is invoked.

2014-02-03ACPI / hotplug / PCI: Remove entries from bus->devices in reverse orderRafael J. Wysocki
According to the changelog of commit 29ed1f29b68a (PCI: pciehp: Fix null pointer deref when hot-removing SR-IOV device) it is unsafe to walk the bus->devices list of a PCI bus and remove devices from it in direct order, because that may lead to NULL pointer dereferences related to virtual functions. For this reason, change all of the bus->devices list walks in acpiphp_glue.c during which devices may be removed to be carried out in reverse order. Signed-off-by: Rafael J.

2014-02-03sata_sil: apply MOD15WRITE quirk to TOSHIBA MK2561GSYNTejun Heo
It's a bit odd to see a newer device showing mod15write; however, the reported behavior is highly consistent and other factors which could contribute seem to have been verified well enough. Also, both sata_sil itself and the drive are fairly outdated at this point making the risk of this change fairly low. It is possible, probably likely, that other drive models in the same family have the same problem; however, for now, let's just add the specific model which was tested.

The cec i2c device is created in tda998x_encoder_init() when the DRM driver starts. This patch frees it when the DRM driver is unloaded.

2014-02-02iwlwifi: mvm: don't allow A band if SKU forbids itEmmanuel Grumbach
The driver wasn't reading the NVM properly. While this didn't lead to any issue until now, it seems that there is an old version of the NVM in the wild. In this version, the A band channels appear to be valid but the SKU capabilities (another field of the NVM) says that A band isn't supported at all. With this specific version of the NVM, the driver would think that A band is supported while the HW / firmware don't. This leads to asserts.

2014-02-01net: ethoc: implement ethtool get/set ring parametersMax Filippov
TX and RX rings share memory and descriptors. Maximal number of descriptors reported is one less than the total available nuber of descriptors. For the set operation the requested number of TX descriptors is rounded down to the nearest power of two (driver logic requirement).
