2015-05-26usb: gadget: f_fs: fix check in read operationRui Miguel Silva1-1/+1
when copying to iter the size can be different then the iov count, the check for full iov is wrong and make any read on request which is not the exactly size of iov to return -EFAULT.

2015-05-26usb: gadget: ffs: fix: Always call ffs_closed() in ffs_data_clear()Krzysztof Opasiak1-5/+8
Originally FFS_FL_CALL_CLOSED_CALLBACK flag has been used to indicate if we should call ffs_closed_callback(). Commit 4b187fceec3c ("usb: gadget: FunctionFS: add devices management code") changed its semantic to indicate if we should call ffs_closed() function which does a little bit more.

x86 has variable length encoding. x86 JIT compiler is trying to pick the shortest encoding for given bpf instruction. While doing so the jump targets are changing, so JIT is doing multiple passes over the program. Typical program needs 3 passes. Some very short programs converge with 2 passes. Large programs may need 4 or 5. But specially crafted bpf programs may hit the pass limit and if the program converges on the last iteration the JIT compiler will be producing an image full of 'int 3' insns.

2015-05-24serial: imx: Fix DMA handling for IDLE condition abortsPhilipp Zabel1-0/+8
The driver configures the IDLE condition to interrupt the SDMA engine. Since the SDMA UART ROM script doesn't clear the IDLE bit itself, this caused repeated 1-byte DMA transfers, regardless of available data in the RX FIFO. Also, when returning due to the IDLE condition, the UART ROM script already increased its counter, causing residue to be off by one. This patch clears the IDLE condition to avoid repeated 1-byte DMA transfers and decreases count by when the DMA transfer was aborted due to the IDLE condition, fixing serial transfers using DMA on i.MX6Q.

2015-05-24serial/amba-pl011: Unconditionally poll for FIFO space before each TX charDave Martin1-8/+8
Commit 734745caeb9f155ab58918834a8c70e83fa6afd3 serial/amba-pl011: (Activate TX IRQ passively) introduces a race which causes the driver sometimes to attempt to write a character to the TX FIFO when the FIFO is already full. The PL011 does not guarantee its behaviour when the FIFO is overfilled. In practice, this can cause duplicate and/or dropped characters to be output on the wire. The problem is common enough to be readily observable on the ARM Juno platform when the PL011 UART is used as the console and DMA is not in use. This patch fixes this problem by always polling for space before each character is written to the FIFO. This will be amended to a less brute-force approach in a later commit, but this patch should help ensure correct behaviour for now.

2015-05-24usb: host: xhci: add mutex for non-thread-safe dataChris Bainbridge2-19/+32
Regression in commit 638139eb95d2 ("usb: hub: allow to process more usb hub events in parallel") The regression resulted in intermittent failure to initialise a 10-port hub (with three internal VL812 4-port hub controllers) on boot, with a failure rate of around 8%, due to multiple race conditions when accessing addr_dev and slot_id in struct xhci_hcd. This regression also exposed a problem with xhci_setup_device, which "should be protected by the usb_address0_mutex" but no longer is due to commit 6fecd4f2a58c ("USB: separate usb_address0 mutexes for each bus") With separate buses (and locks) it is no longer the case that a single lock will protect xhci_setup_device from accesses by two parallel threads processing events on the two buses. Fix this by adding a mutex to protect addr_dev and slot_id in struct xhci_hcd, and by making the assignment of slot_id atomic. Fixes multiple boot errors: [ 0.583008] xhci_hcd 0000:00:14.0: Bad Slot ID 2 [ 0.583009] xhci_hcd 0000:00:14.0: Could not allocate xHCI USB device data structures [ 0.583012] usb usb1-port3: couldn't allocate usb_device And: [ 0.637409] xhci_hcd 0000:00:14.0: Error while assigning device slot ID [ 0.637417] xhci_hcd 0000:00:14.0: Max number of devices this xHCI host supports is 32.

2015-05-24usb: make module xhci_hcd removableArthur Demchenkov1-0/+8
Fixed regression. After commit 29e409f0f761 ("xhci: Allow xHCI drivers to be built as separate modules") the module xhci_hcd became non-removable. That behaviour is not expected and there're no notes about it in commit message. The module should be removable as it blocks PM suspend/resume functions (Debian Bug#666406).

2015-05-24Revert "ALSA: hda - Add mute-LED mode control to Thinkpad"Takashi Iwai1-1/+0
This reverts commit 7290006d8c0900c56d8c58428134f02c35109d17. Through the regression report, it was revealed that the tpacpi_led_set() call to thinkpad_acpi helper doesn't only toggle the mute LED but actually mutes the sound. This is contradiction to the expectation, and rather confuses user. According to Henrique, it's not trivial to judge which TP model behaves "LED-only" and which model does whatever more intrusive, as Lenovo's implementations vary model by model. So, from the safety reason, we should revert the patch for now.
