2016-07-01net/mlx5e: Fix select queue callbackRana Shahout
The default fallback function used by mlx5e select queue can return any TX queues in range [0..dev->num_real_tx_queues). The current implementation assumes that the fallback function returns a number in the range [0.. number of channels). Actually dev->num_real_tx_queues = (number of channels) * dev->num_tc; which is more than the expected range if num_tc is configured and could lead to crashes. To fix this we test if num_tc is not configured we can safely return the fallback suggestion, if not we will reciprocal_scale the fallback result and normalize it to the desired range.

2016-07-01net/mlx5e: Handle RQ flush in error casesDaniel Jurgens
Add a timeout to avoid an infinite loop waiting for RQ's to flush.

2016-07-01net/mlx5: Add timeout handle to commands with callbackMohamad Haj Yahia
The current implementation does not handle timeout in case of command with callback request, and this can lead to deadlock if the command doesn't get fw response. Add delayed callback timeout work before posting the command to fw. In case of real fw command completion we will cancel the delayed work. In case of fw command timeout the callback timeout handler will be called and it will simulate fw completion with timeout error.

2016-07-01net/mlx5: Avoid calling sleeping function by the health poll threadMohamad Haj Yahia
In internal error state the health poll thread will eventually call synchronize_irq() (to safely trigger command completions) which might sleep, so we are calling sleeping function from atomic context which is invalid. Here we move trigger_cmd_completions(dev) to enter error state which is the earliest stage in error state handling. This way we won't need to wait for next health poll to trigger command completions and will solve the scheduling while atomic issue. mlx5_enter_error_state can be called from two contexts, protect it with dev->intf_state_lock Fixes: 89d44f0a6c73 ('net/mlx5_core: Add pci error handlers to mlx5_core driver') Signed-off-by: Mohamad Haj Yahia <mohamad@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.

2016-07-01intel_th: Add runtime power management handlingAlexander Shishkin
Currently, an Intel TH (pci) device will be always active, because the devices on the 'intel_th' bus don't implement runtime pm to track their usage. To address this, this patch adds runtime pm support to the 'intel_th' bus and some additional bits for the hub. The 'output' type device is in use while a capture is active; the 'source' type device (STH) relies on its child stm class device for runtime pm tracking.

2016-06-30iio: magn: ak8975: deploy runtime and system PMLinus Walleij
This adds runtime PM support to the AK8975 driver. It solves two problems: - After reading the first value the chip was left in MODE_ONCE, meaning (presumably) it may be consuming more power. Now the runtime PM hooks kick in and set it to POWER_DOWN. - Regulators were simply enabled and left on, making it impossible to turn the power consuming regulators off because of the increased refcount. We now disable the regulators at autosuspend. - We also handle system suspend: by using pm_runtime_force_suspend() and pm_runtime_force_resume() from the system PM sleep hooks, the runtime PM code is managing the power also for this case. It is currently not completely optimal: when the system resumes the AK8975 goes into active mode even if noone is going to use it: currently the force calls need to be paired, but the runtime PM people are working on making it possible to leave devices runtime suspended when coming back from sleep.

When MTU is changed unlink_urbs() flushes RX Q but mean while usbnet_bh() can fill up the Q at the same time. Depends on which HCD is down there unlink takes long time then the flush never ends.

Jarod Wilson's fix for e1000e was a follow-on patch to his previous fix to keep the hardware VLAN CTAG's for receive and transmit in sync, which in turn resolves the original issue, so revert a portion of the original fix. Xin Long noticed that the ret_val needed to be initialized to IXGBE_ERR_MBX, instead of -IXGBE_ERR_MBX. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2016-06-30mfd: max77620: Fix FPS switch statementsRhyland Klein
When configuring FPS during probe, assuming a DT node is present for FPS, the code can run into a problem with the switch statements in max77620_config_fps() and max77620_get_fps_period_reg_value(). Namely, in the case of chip->chip_id == MAX77620, it will set fps_[mix|max]_period but then fall through to the default switch case and return -EINVAL. Returning this from max77620_config_fps() will cause probe to fail.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second round of new iio device support, features and cleanups in the 4.8 cycle Firstly some contact detail updates: * NXP took over freescale. Update the mma8452 header to reflect this. * Martin Kepplinger email address change in mma8452 header. * Adriana Reus has changed email address. Update .mailmap. * Matt Ranostay has changed email address. Update .mailmap. New Device Support * max1363 - add the missing i2c_device_ids for a couple of parts so they can actually be used. * ms5867 - add device ids for ms5805 and ms5837 parts. New Features * ad5755 - DT support. This one was a bit controversial and under review for a long time. Still no one could come up with a better solution. * stx104 - add gpio support * ti-adc081c - Add ACPI device ID matching. Core changes * Refuse to register triggers with duplicate names. There is no way to distinguish between them so this makes no sense. A few drivers do not generate unique names for each instance of the device present. We can't fix this without changing ABI so leave them and wait for someone to actually take the rare step of two identical accelerometers on the same board. * buffer-dma - use ARRAY_SIZE in a few appropriate locations. Tools * Fix the fact that the --trigger-num option in generic_buffer didn't allow 0 which is perfectly valid in the ABI. Cleanups * as3935 - improve error reporting. - remove redundant zeroing of a field in iio_priv. * gp2ap020a00f - use the iio_device_claim_*_mode helpers rather than open coding locking around mode changes. * isl29125 - use the iio_device_claim_*_mode helpers rather than open coding locking. * lidar - use the iio_device_claim_*_mode helpers rather than open coding locking. * mma8452 - more detail in devices supported description in comments (addresses and similar) * sca3000 - add a missing error check. * tcs3414 - use the iio_device_claim_*_mode helpers rather than open coding locking. * tcs3472 - use the iio_device_claim_*_mode helpers rather than open coding locking.
