2011-06-29tegra: usb: prevent crash if irq occurs while sleepingAlexandre Courbot
In some rare cases, EHCI irqs interrupts be triggered while the block is suspended. This is notably the case when unplugging a host cable to which no device is attached. In this case, the interrupt handler will be called with the block powered off, which will eventually crash. This patch workarounds this by returning from the interrupt handler immediatly if the block is not powered on.

2011-06-21tegra: usb: fix ehci suspend in host modeAlexandre Courbot
When suspend is called and usb1 is in host mode, tegra_hci_remove is invoked to remove the device. However, at this time it is likely that runtime PM will have powered off usb1. This patch ensures usb1 is powered on if necessary within tegra_hci_remove so that ehci controller registers can be manipulated. Bug 835677.

2011-02-25USB: gadget: f_mtp: dequeue request on error in mtp_readMike Lockwood
In mtp_read(), if wait_event_interruptible() returns an error, we need to remove the request from the EP queue. Else, on the next call to mtp_read(), we will attempt to enqueue the request again, potentially corrupting the queue. This is what happens with musb_gadget_queue(), which does not check for duplicate requests. Based on a similar change to f_adb.c Signed-off-by: Mike Lockwood <lockwood@android.com>
