"ocfs2 syncs the wrong range" had been broken; prior to it the
code was doing the wrong thing in case of O_APPEND, all right,
but _after_ it we were syncing the wrong range in 100% cases.
*ppos, aka iocb->ki_pos is incremented prior to that point,
so we are always doing sync on the area _after_ the one we'd
written to.

of_find_node_by_name() calls of_node_put() on its "from" parameter.
To counter this, pm860x_backlight_dt_init() calls of_node_get() first.
Use of_get_child_by_name() instead to get rid of the refcount hack.

The RTC on S2MPS11 is the same as S2MPS14. However interrupt numbers of
RTC alarms 0 and 1 were inversed between these two devices. So when
rtc-s5m driver requested S2MPS14_IRQ_RTCA0 interrupt, it matched to
S2MPS11_IRQ_RTCA1, not RTCA0.
Fix this by using consistent RTC alarm interrupt numbers and adding a
BUILD_BUG_ON for future generations.

Even if bus is not hot-pluggable, the devices can be unbound from the

The comment line regarding IOMMU_INIT and IOMMU_INIT_FINISH
macros is incorrect:
"The standard vs the _FINISH differs in that the _FINISH variant
will continue detecting other IOMMUs in the call list..."
It should be "..the *standard* variant will continue

Wrap asm/jump_label.h for all archs with #ifndef __ASSEMBLY__.
Since these are kernel only headers, we don't need #ifdef
__KERNEL__ so can simplify things a bit.
If an architecture wants to use jump labels in assembly, it
will still need to define a macro to create the __jump_table
entries (see ARCH_STATIC_BRANCH in the powerpc asm/jump_label.h
for an example).

Currently it is not possible to use 'mmc-pwrseq-simple' property with this
driver because mmc_of_parse() is never called.
mmc_of_parse() calls mmc_pwrseq_alloc() that manages MMC power sequence and
allows passing GPIOs in the devicetree to properly power/reset the Wifi
chipset.
When using mmc_of_parse() we no longer need to have custom code to request
card-detect and write-protect pins, as this can now be handled by the mmc
core.
Tested on a imx6sl-warp board where BT/Wifi is functional and also on a
imx6q-sabresd.

It is possible for the cmd11 interrupt to fire and delete the

Although the cmd11 interrupt should come within 2ms, that's a very
short time. Let's increase the timeout to be really sure that we
don't get an accidnetal timeout. One case in particular this is
useful is if you've got a serial console and printk in just the right
places. Under that scenario I've seen delays of up to 130ms before
the interrupt fired.
CMD11 is only sent during card insertion, so this extra timeout
shouldn't be terrible.

The dw_mmc driver changes to make the IO accesors endian agnostic did not
take into account the fifo accesses do not need to be swapped. To fix this
add a mmci_fifo_read/write wrapper to allow these to be passed through the
IO without being swapped.
Since these are now specific functions, it would be easier just to store
the pointer to the fifo registers in the host block instead of the offset
to them. So change the host->data_offset to host->fifo_reg (which also
means we catch all the places this is read or written).

Similar to what Linus suggested for rwsem_spin_on_owner(), in
mutex_spin_on_owner() instead of having while (true) and
breaking out of the spin loop on lock->owner != owner, we can
have the loop directly check for while (lock->owner == owner) to
improve the readability of the code.
It also shrinks the code a bit:

When establishing a Bluetooth LE connection, read the remote used
features mask to determine which features are supported. This was
not really needed with Bluetooth 4.0, but since Bluetooth 4.1 and
also 4.2 have introduced new optional features, this becomes more
important.
This works the same as with BR/EDR where the connection enters the
BT_CONFIG stage and hci_connect_cfm call is delayed until the remote
features have been retrieved. Only after successfully receiving the
remote features, the connection enters the BT_CONNECTED state.

Thermal framework may already be ready and cooling policies might
already be functional when we are attempting to register gpio fan as
a cooling device. This can be reproduced by changing probe order in
which registration of various modules are done in a system. In such
a case, kernel generates an oops since the data structures are not
completely populated with the wrong assumption that thermal framework
is not yet ready. Fix this by reordering the thermal framework
registration to occur after hwmon registration of the fan is complete.
Example kernel oops:

FastOpen requests are not like other regular request sockets.
They do not yet use rsk_timer : tcp_fastopen_queue_check()
simply manually removes one expired request from fastopenq->rskq_rst
list.
Therefore, tcp_check_req() must not call mod_timer_pending(),
otherwise we crash because rsk_timer was not initialized.
