2011-05-02mfd: Fix usbhs_enable error handlingAxel Lin1-5/+3
In the case of missing platform_data we do not hold a spin_lock, thus we should not call spin_unlock_irqrestore in the error path. Also simplify the error handling by separating the successful path from error path. I think this change improves readability.

2011-05-02usb: musb: gadget: Fix out-of-sync runtime pm callsJarkko Nikula1-4/+2
If cable is not connected to peripheral only board when initializing the gadget driver, then runtime pm calls are out-of-sync and the musb cannot idle with omap2430.c. This was noted on Nokia N900 where musb prevented the CPU to be able to enter deeper retention idle state. This was working in 2.6.38 before runtime pm conversions but there musb smart standby/idle modes were configured statically where they are now updated runtime depending on use and cable status. Reason for out-of-sync is that runtime pm is activated in function musb_gadget.c: usb_gadget_probe_driver but suspended only in OTG mode if cable is not connected when initializing. In peripheral only mode this leads to out-of-sync runtime pm since runtime pm remain active and is activated another time in omap2430.c: musb_otg_notifications for VBUS Connect event and thus cannot suspend for VBUS Disconnect event since the use count remains active. Fix this by moving cable status check and pm_runtime_put call in usb_gadget_probe_driver out of is_otg_enabled block.

2011-05-02usb: musb: omap2430: Fix retention idle on musb peripheral only boardsJarkko Nikula1-1/+1
Recent runtime pm and hwmod conversions for 2.6.39 broke the musb peripheral mode OMAP retention idle on boards where the board mode in struct musb_hdrc_platform_data is set to MUSB_PERIPHERAL. These conversions changed the way how the OTG_SYSCONFIG register is configured and used in runtime. Before 2.6.39 smart standby/idle modes were activated statically in OTG_SYSCONFIG. Those modes allow that the musb is able to idle when peripheral device is not connected to host. In 2.6.39 the OTG_SYSCONFIG is updated runtime depending on VBUS status. No standby/idle modes are used when device is connected and force standby/idle when disconnected. Unfortunately VBUS disconnect event that handles the disconnect case lets the peripheral musb to idle only when board mode is MUSB_OTG. Fix this by checking the peripheral mode also.

2011-05-02Revert "ALSA: hda - Fix pin-config of Gigabyte mobo"Takashi Iwai1-18/+3
This reverts commit c6b358748e19ce7e230b0926ac42696bc485a562. It turned out that there are different pin configurations for this PCI SSID, including multi-channel modes. And more proper fix for allowing line-out mutes will come up in 2.6.40 tree, so we won't need this fixup any more there.

2011-05-01x86, NUMA: Fix empty memblk detection in numa_cleanup_meminfo()Yinghai Lu1-1/+1
numa_cleanup_meminfo() trims each memblk between low (0) and high (max_pfn) limits and discards empty ones. However, the emptiness detection incorrectly used equality test. If the start of a memblk is higher than max_pfn, it is empty but fails the equality test and doesn't get discarded. The condition triggers when max_pfn is lower than start of a NUMA node and results in memory misconfiguration - leading to WARN_ON()s and other funnies. The bug was discovered in devel branch where 32bit too uses this code path for NUMA init. If a node is above the addressing limit, max_pfn ends up lower than the node triggering this problem. The failure hasn't been observed on x86-64 but is still possible with broken hardware e820/NUMA info. As the fix is very low risk, it would be better to apply it even for 64bit. Fix it by using >= instead of ==.

2011-05-01x86, AMD: Fix APIC timer erratum 400 affecting K8 Rev.A-E processorsBoris Ostrovsky1-1/+1
Older AMD K8 processors (Revisions A-E) are affected by erratum 400 (APIC timer interrupts don't occur in C states greater than C1). This, for example, means that X86_FEATURE_ARAT flag should not be set for these parts. This addresses regression introduced by commit b87cf80af3ba4b4c008b4face3c68d604e1715c6 ("x86, AMD: Set ARAT feature on AMD processors") where the system may become unresponsive until external interrupt (such as keyboard input) occurs. This results, for example, in time not being reported correctly, lack of progress on the system and other lockups.

2011-04-29USB: add queued-unlinks test case to usbtest driverAlan Stern1-2/+118
This patch (as1452b) adds a new test case to the usbtest driver. Test 24 exercises the unlink-from-queue pathways in the host. It queues a user-specified number of bulk-OUT URBs of user-specified size, unlinks the fourth- and second-from-last URBs in the queue, and then waits to see if all the URBs complete in the expected way (except of course that the unlinked URBs might complete normally, if they weren't unlinked soon enough). This new test has confirmed the existence of a bug in the ehci-hcd driver, to be fixed by a separate patch.

In this situation, driver will create new pipe without caring old pipe if "usbhsg_ep_enable" is called after "usbhsg_ep_disable" on current driver. This mean the limited pipe and buffer will be used as waste. But it is possible to re-use same buffer to same pipe.
