The function stmmac_dt_phy provides several possibilities for initializing
plat->mdio_node, all of which have the effect of increasing the reference
count of the assigned value. This field is not updated elsewhere, so the
value is live until the end of the lifetime of plat (devm_allocated), just
after the end of stmmac_remove_config_dt. Thus, add an of_node_put on
plat->mdio_node in stmmac_remove_config_dt. It is possible that the field
mdio_node is never initialized, but of_node_put is NULL-safe, so it is also
safe to call of_node_put in that case.

This patch part reverts fd2a0437dc33 and e858fae2b0b8 which introduced a
subtle change in how the virtio_net flags are derived from the SKBs
ip_summed field.
With the above commits, the flags are set to VIRTIO_NET_HDR_F_DATA_VALID
when ip_summed == CHECKSUM_UNNECESSARY, thus treating it differently to
ip_summed == CHECKSUM_NONE, which should be the same.
Further, the virtio spec 1.0 / CS04 explicitly says that
VIRTIO_NET_HDR_F_DATA_VALID must not be set by the driver.

Zoned block devices force the use of READ/WRITE(16) commands by setting
sdkp->use_16_for_rw and clearing sdkp->use_10_for_rw. This result in
DPOFUA always being disabled for these drives as the assumed use of
the deprecated READ/WRITE(6) commands only looks at sdkp->use_10_for_rw.
Strenghten the test by also checking that sdkp->use_16_for_rw is false.

As done previously for sun4i-codec, the DMA maxburst of 4
is not supported by every SoCs so the DMA controller engine
returns "unsupported value".
As a maxburst of 8 is supported by all variants, this patch
increases it to 8.

The SAIF base oversample rates are either 512*fs or 384*fs. An additional
divider exists within the SAIF to generate sub-multiples of these two base
rates if MCLK is required by the codec.
* The sub-rates for the 512x base rate are: 256x, 128x, 64x, and 32x.
* The sub-rates for the 384x base rate are: 192x, 96x, and 48x.
Setting the base rate depending on the modulo operation with 32 and 48
give wrong results for some mclk.
If mclk=18.432MHz both modulo operations results in 0. As testing the
result with 32 is done first, a wrong base rate of 512*fs is set instead
of the correct 384*fs.
Fix this by setting the base rate depending on the calculated sub-rate.

This starts to handle probe deferrals on regulators and clocks
on the ASoC DAPM.
I came to this patch after audio stopped working on Ux500 ages
ago and I finally looked into it to see what is wrong. I had
messages like this in the console since a while back:
ab8500-codec.0: ASoC: Failed to request audioclk: -517
ab8500-codec.0: ASoC: Failed to create DAPM control audioclk
ab8500-codec.0: Failed to create new controls -12
snd-soc-mop500.0: ASoC: failed to instantiate card -12
snd-soc-mop500.0: Error: snd_soc_register_card failed (-12)!
snd-soc-mop500: probe of snd-soc-mop500.0 failed with error -12
Apparently because the widget table for the codec looks like
this (sound/soc/codecs/ab8500-codec.c):
static const struct snd_soc_dapm_widget ab8500_dapm_widgets[] = {
/* Clocks */
SND_SOC_DAPM_CLOCK_SUPPLY("audioclk"),
/* Regulators */
SND_SOC_DAPM_REGULATOR_SUPPLY("V-AUD", 0, 0),
SND_SOC_DAPM_REGULATOR_SUPPLY("V-AMIC1", 0, 0),
SND_SOC_DAPM_REGULATOR_SUPPLY("V-AMIC2", 0, 0),
SND_SOC_DAPM_REGULATOR_SUPPLY("V-DMIC", 0, 0),
So when we call snd_soc_register_codec() and any of these widgets
get a deferred probe we do not get an -EPROBE_DEFER (-517) back as
we should and instead we just fail. Apparently the code assumes
that clocks and regulators must be available at this point and
not defer.
After this patch it rather looks like this:
ab8500-codec.0: Failed to create new controls -517
snd-soc-mop500.0: ASoC: failed to instantiate card -517
snd-soc-mop500.0: Error: snd_soc_register_card failed (-517)!
(...)
abx500-clk.0: registered clocks for ab850x
snd-soc-mop500.0: ab8500-codec-dai.0 <-> ux500-msp-i2s.1 mapping ok
snd-soc-mop500.0: ab8500-codec-dai.1 <-> ux500-msp-i2s.3 mapping ok
I'm pretty happy about the patch as it it, but I'm a bit
uncertain on how to proceed: there are a lot of users of the
external functions snd_soc_dapm_new_control() (111 sites)
and that will now return an occassional error pointer, which
is not handled in the calling sites.
I want an indication from the maintainers whether I should just
go in and augment all these call sites, or if deferred probe
is frowned upon when it leads to this much overhead.

Intel Broadwell machine driver will call API snd_soc_set_dmi_name() to
use DMI info to make the sound card long name.
For example, here are the changed long name for two Broadwell-based
machines:
Dell XPS-13(2015): DellInc.-XPS139343-01-0310JH
Intel WilsonBeach: Intel Corp.-BroadwellClientplatform-0.1-WilsonBeachSDS

Intel DSP platform drivers are used by many different devices but are
difficult for userspace to differentiate. This patch adds an API to allow
the DMI name to be used in the sound card long name, thereby helping
userspace load the correct UCM configuration. Usually machine drivers
uses their own name as the sound card name (short name), and leave the
long name and driver name blank. This API will use the DMI info like
vendor, product and board to make up the card long name. If the machine
driver has already explicitly set the long name, this API will do nothing.
This patch also allows for further differentiation as many devices that
share the same DMI name i.e. Minnowboards, UP boards may be configured
with different codecs or firmwares. The API supports flavoring the DMI
name into the card longname to provide the extra differentiation required
for these devices.
For Use Case Manager (UCM) in the user space, changing card long name by
this API is backward compatible, since the card name does not change. For
a given sound card, even if there is no device-specific UCM configuration
file that uses the card long name, UCM will fall back to load the default
configuration file that uses the card name.

Rename SND_SST_MFLD_PLATFORM to SND_SST_ATOM_HIFI2_PLATFORM to make it clear
that is not only about Medfield platform.
The new name is derived from Intel Atom and HiFi2. HiFi2 is the DSP version,
it's public information for Intel *Field/*Trail parts, see
https://www.alsa-project.org/main/index.php/Firmware. By combining HiFi2 with
Atom we get a unique non-ambiguous description of the core+DSP hardware for
Intel Medfield through Intel Cherrytrail.

When replaying the journal it can happen that a journal entry points to
a garbage collected node.
This is the case when a power-cut occurred between a garbage collect run
and a commit. In such a case nodes have to be read using the failable
read functions to detect whether the found node matches what we expect.
One corner case was forgotten, when the journal contains an entry to
remove an inode all xattrs have to be removed too. UBIFS models xattr
like directory entries, so the TNC code iterates over
all xattrs of the inode and removes them too. This code re-uses the
functions for walking directories and calls ubifs_tnc_next_ent().
ubifs_tnc_next_ent() expects to be used only after the journal and
aborts when a node does not match the expected result. This behavior can
render an UBIFS volume unmountable after a power-cut when xattrs are
used.
Fix this issue by using failable read functions in ubifs_tnc_next_ent()
too when replaying the journal.

In several places, ubifs checked for an encryption key before creating a
file in an encrypted directory. This was redundant with
fscrypt_setup_filename() or ubifs_new_inode(), and in the case of
ubifs_link() it broke linking to special files. So remove the extra
checks.

The ubifs encryption ioctls did not work when called by a 32-bit program
on a 64-bit kernel. Since 'struct fscrypt_policy' is not affected by
the word size, ubifs just needs to allow these ioctls through, like what
ext4 and f2fs do.

This came up during the v4.10 merge window:
warning: (UBIFS_FS_ENCRYPTION) selects FS_ENCRYPTION which has unmet direct dependencies (BLOCK)
fs/crypto/crypto.c: In function 'fscrypt_zeroout_range':
fs/crypto/crypto.c:355:9: error: implicit declaration of function 'bio_alloc';did you mean 'd_alloc'? [-Werror=implicit-function-declaration]
bio = bio_alloc(GFP_NOWAIT, 1);
The easiest way out is to limit UBIFS_FS_ENCRYPTION to configurations
that also enable BLOCK.

This reverts commit 4c81acab3816 ("bcma: init serial console directly
from ChipCommon code") as it broke IRQ assignment. Getting IRQ with
bcma_core_irq helper on SoC requires MIPS core to be set. It happens
*after* ChipCommon initialization so we can't do this so early.
This fixes a user reported regression. It wasn't critical as serial was
still somehow working but lack of IRQs was making in unreliable.

Commit b67a8b29df introduced logic to skip swiotlb allocation when all memory
is DMA accessible anyway.
While this is a great idea, __dma_alloc still calls swiotlb code unconditionally
to allocate memory when there is no CMA memory available. The swiotlb code is
called to ensure that we at least try get_free_pages().
Without initialization, swiotlb allocation code tries to access io_tlb_list
which is NULL. That results in a stack trace like this:
Unable to handle kernel NULL pointer dereference at virtual address 00000000

Thankfully swiotlb code just learned how to not do allocations with the FORCE_NO
option. This patch configures the swiotlb code to use that if we decide not to
initialize the swiotlb framework.

By failing to set the errno, we'd continue on to trying to set up the
RCL, and then oops on trying to dereference the tile_bo that binning
validation should have set up.

We copy the unvalidated ioctl arguments from the user into kernel
temporary memory to run the validation from, to avoid a race where the
user updates the unvalidate contents in between validating them and
copying them into the validated BO.
However, in setting up the layout of the kernel side, we failed to
check one of the additions (the roundup() for shader_rec_offset)
against integer overflow, allowing a nearly MAX_UINT value of
bin_cl_size to cause us to under-allocate the temporary space that we
then copy_from_user into.
