If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.
Export the module alias information using the MODULE_DEVICE_TABLE() macro.

$ $ modinfo drivers/watchdog/max77620_wdt.ko | grep alias

Commit 3b3f1650b1ca ("drm/i915: Allocate intel_engine_cs
structure only for the enabled engines") introduced the
dynanically allocated engine instances and created an
potential use after free scenario in logical_render_ring_init
where lrc_destroy_wa_ctx_obj could be called after the engine
instance has been freed.
This can only happen during engine setup/init error handling
which luckily does not happen ever in practice.
Fix is to not call lrc_destroy_wa_ctx_obj since it would have
already been executed from the preceding engine cleanup.

A complement to drm_mm_for_each_node(), wraps list_for_each_entry_safe()
for walking the list of nodes safe against removal.

"Most of the diff is about __drm_mm_nodes(mm), which could be split into

Currently, inner IV/DIGEST data are only copied once into the hash
engines and not set explicitly before launching a request that is not a
first frag. This is an issue especially when multiple ahash reqs are
computed in parallel or chained with cipher request, as the state of the
request being computed is not updated into the hash engine. It leads to
non-deterministic corrupted digest results.

If iscsit_tpg_add_network_portal() fails then
return error code instead of 0 to user space.
If iscsi-target returns 0 then user space keeps
on retrying same command infinitely, targetcli or
echo hangs till command completes with non zero
return value. In some cases it is possible that
add network portal command never completes with
success even after retrying multiple times,
for example - cxgbit_setup_np() always returns
-EINVAL if portal IP does not belong to Chelsio

This iscsit_tpg_add_portal_group() function is only called from

Previously to read/write a GPA, we at first try to pin the GFN it belongs
to, then translate the pinned PFN to a kernel HVA, then read/write it.
This is however not necessary. A GFN should be pinned IFF it would be
accessed by peripheral devices (DMA), not by CPU. This patch changes
the read/write method to KVM API, which will leverage userspace HVA
and copy_{from|to}_usr instead.

other trees or has had it available for a while, so this is where

- TP-LINK Archer C9 V1
- Luxul XAP-1510 Access point
- Turris Omnia open hardware router based on Armada 385
And a couple of new boards targeted at developers, makers or
industrial integration:
- Macnica Sodia development platform for Altera socfpga (Cyclone V)
- MicroZed board based on Xilinx Zynq FPGA platforms
- TOPEET itop/elite based on exynos4412
- WP8548 MangOH Open Hardware platform for IOT, based on Qualcomm MDM9615

This patch introduces virtio-crypto driver for Linux Kernel.
The virtio crypto device is a virtual cryptography device
as well as a kind of virtual hardware accelerator for
virtual machines. The encryption anddecryption requests
are placed in the data queue and are ultimately handled by
thebackend crypto accelerators. The second queue is the
control queue used to create or destroy sessions for
symmetric algorithms and will control some advanced features
in the future. The virtio crypto device provides the following
cryptoservices: CIPHER, MAC, HASH, and AEAD.
For more information about virtio-crypto device, please see:

When event index was enabled, we need to fetch used event from
userspace memory each time. This userspace fetch (with memory
barrier) could be saved sometime when 1) caching used event and 2)
if used event is ahead of new and old to new updating does not cross
it, we're sure there's no need to notify guest.
This will be useful for heavy tx load e.g guest pktgen test with Linux
driver shows ~3.5% improvement.

There is basically no shared logic between the INTx and MSI-X case in
vp_try_to_find_vqs, so split the function into two and clean them up
a little bit.
Also remove the fairly pointless vp_request_intx wrapper while we're at it.

vp_request_msix_vectors is only called by vp_try_to_find_vqs, which already
calls vp_free_vectors through vp_del_vqs in the failure case.

This avoids the separate allocation for the msix_entries structures, and
instead allows us to use pci_irq_vector to find a given IRQ vector.

We call del_vqs twice when request_irq fails, this
makes no sense.

Pull i2c updates from Wolfram Sang:
- the first series of making i2c_device_id optional instead of
mandatory (in favor of alternatives like of_device_id).
This involves adding a new probe callback (probe_new) which removes
some peculiarities I2C had for a long time now. The new probe is
matching the other subsystems now and the old one will be removed
once all users are converted. It is expected to take a while but
there is ongoing interest in that.
- SMBus Host Notify introduced 4.9 got refactored. They are now using
interrupts instead of the alert callback which solves multiple
issues.
- new drivers for iMX LowPower I2C, Mellanox CPLD and its I2C mux
- significant refactoring for bcm2835 driver
- the usual set of driver updates and improvements

linux-next reported in_tablet_mode and type may be used uninitialized
after:
b31800283868 ("platform/x86: thinkpad_acpi: Move tablet detection into separate function")
This turns out to be a false positive as the pr_info call cannot be
reached if tp_features.hotkey_tablet (global scope) is 0, and
in_tablet_mode and type are assigned in both places
tp_features.hotkey_tablet is assigned.
Regardless, to make it explicit and avoid further reports, initialize
in_tablet_mode to 0 and type to NULL.
