2011-12-19usb: gadget: epautoconf: do not change number of streamsFelipe Balbi1-3/+0
We should not change gadget driver's descriptors just because we think it's right to do so. There are several of reasons which would support this statement but it suffices to say that this was probably never tested because it updates bmAttributes without asking the driver if it's ok to do so. This means that e.g. on UASP gadget it would enable stream support even for the command endpoint which must not have stream support enabled. In fact, this change is fixing the bug introduced by commit a59d6b9 (usb: gadget: add streams support to the gadget framework) which was caught when testing UASP gadget with dwc3 driver.

2011-12-18Bluetooth: Clear RFCOMM session timer when disconnecting last channelMat Martineau1-0/+1
When the last RFCOMM data channel is closed, a timer is normally set up to disconnect the control channel at a later time. If the control channel disconnect command is sent with the timer pending, the timer needs to be cancelled. If the timer is not cancelled in this situation, the reference counting logic for the RFCOMM session does not work correctly when the remote device closes the L2CAP connection. The session is freed at the wrong time, leading to a kernel panic. Signed-off-by: Mat Martineau <[email protected]> Acked-by: Marcel Holtmann <[email protected]> Signed-off-by: Gustavo F.

2011-12-18pci: Fix hotplug of Express Module with pci bridgesYinghai Lu1-1/+5
I noticed that hotplug of one setup does not work with recent change in pci tree. After checking the bridge conf setup, I noticed that the bridges get assigned but do not get enabled. The reason is the following commit, while simply ignores bridge resources when enabling a pci device: | commit bbef98ab0f019f1b0c25c1acdf1683c68933d41b | Author: Ram Pai <[email protected]> | Date: Sun Nov 6 10:33:10 2011 +0800 | | PCI: defer enablement of SRIOV BARS |... | NOTE: Note, there is subtle change in the pci_enable_device() API. Any | driver that depends on SRIOV BARS to be enabled in pci_enable_device() | can fail. Put back bridge resource and ROM resource checking to fix the problem. That should fix regression like BIOS does not assign correct resource to bridge.

Commit 5c48b108 ("um: take arch/um/sys-x86 to arch/x86/um") broke the make target update-po-config, as its symlink trick (again) fails. (Previous breakage was fixed with commit bdc69ca4 ("kconfig: change update-po-config to reflect new layout of arch/um").) The new UML layout allows to drop the symlick trick entirely. And if, one day, another architecture supports UML too, that should now work without again breaking this make target.

Before registering an adapter to i2c subsystem, we need make sure driver is ready for incoming i2c xfer, becasue the i2c_add_adapter() may trigger a i2c device driver's proble function which may start some real i2c xfer. I met this issue when integrating a TSC2007 i2c touch screen device with the i2c-eg20t driver. This patch will call request_irq() and hw init before calling i2c_add_adapter().

RC6 should always work on IVB, and should work on SNB whenever IO remapping is disabled. RC6 never works on Ironlake. Make the default value for the parameter follow these guidelines. Setting the value to either 0 or 1 will force the specified behavior.

2011-12-16iommu: Export intel_iommu_enabled to signal when iommu is in useEugeni Dodonov2-0/+7
In i915 driver, we do not enable either rc6 or semaphores on SNB when dmar is enabled. The new 'intel_iommu_enabled' variable signals when the iommu code is in operation.

2011-12-16drm/i915/sdvo: Include LVDS panels for the IS_DIGITAL checkChris Wilson1-8/+20
We were checking whether the supplied edid matched the connector it was read from. We do this in case a DDC read returns an EDID for another device on a multifunction or otherwise interesting card. However, we failed to include LVDS as a digital device and so rejecting an otherwise valid EDID. Fixes the detection of the secondary SDVO LVDS panel on the Libretto W105.

2011-12-16drm/i915: prevent division by zero when asking for chipset powerEugeni Dodonov2-0/+11
This prevents an in-kernel division by zero which happens when we are asking for i915_chipset_val too quickly, or within a race condition between the power monitoring thread and userspace accesses via debugfs. The issue can be reproduced easily via the following command: while ``; do cat /sys/kernel/debug/dri/0/i915_emon_status; done This is particularly dangerous because it can be triggered by a non-privileged user by just reading the debugfs entry. This issue was also found independently by Konstantin Belousov <[email protected]>, who proposed a similar patch.
