In this function, once 'buf' has been allocated, we unconditionally
return 0.
However, 'error' is set to some error codes in several error handling
paths.
Before commit 232b51948b99 ("xfs: simplify the xfs_getbmap interface")
this was not an issue because all error paths were returning directly,
but now that some cleanup at the end may be needed, we must propagate the
error code.

Since the commit c647f806b8c2 ("ALSA: hda - Allow multiple ADCs for
mic mute LED controls") we allow enabling the mic mute LED with
multiple ADCs. The commit changed the function return value to be
zero or a negative error, while this change was overlooked in the
thinkpad_acpi helper code where it still expects a positive return
value for success. This eventually leads to a NULL dereference on a
system that has only a mic mute LED.
This patch corrects the return value check in the corresponding code
as well.

We deinit the lpe audio device before we call
drm_atomic_helper_shutdown(), which means the platform device
may already be gone when it comes time to shut down the crtc.
As we don't know when the last reference to the platform
device gets dropped by the audio driver we can't assume that
the device and its data are still around when turning off the
crtc. Mark the platform device as gone as soon as we do the
audio deinit.

these FIXME cases here.
So I got the confirmation from HW architect that we actually
never needed this workaround.

The 16Gb DIMM w/a is not applicable to BXT or GLK. Limit it to
the appropriate platforms.
This was especially harsh on GLK since we don't even try to read
the DIMM information on that platforms, hence valid_dimm was
always false and thus we always tried to apply the w/a.
Furthermore the w/a pushed the level 0 latency above the
level 1 latency, which doesn't really make sense.

The documentation for the .raw_event() callback says that if the
driver return 1, there will be no further processing of the event,
but this is not true, the actual code in hid-core.c looks like this:
if (hdrv && hdrv->raw_event && hid_match_report(hid, report)) {
ret = hdrv->raw_event(hid, report, data, size);
if (ret < 0)
goto unlock;
}
ret = hid_report_raw_event(hid, type, data, size, interrupt);
The only return value that has any effect on the processing is
a negative error.
Correct this as it seems to confuse people: I found bogus code in
the Razer out-of-tree driver attempting to return 1 here.

asus_wmi_evaluate_method() is an empty dummy function when CONFIG_ASUS_WMI

The following patchset contains the first batch of Netfilter fixes for

2) Fix Incorrect check for missing attribute in nft_osf.
3) Missing INT_MIN & INT_MAX definition for netfilter bridge uapi
header, from Jiri Slaby.
4) Revert map lookup in nft_numgen, this is already possible with
the existing infrastructure without this extension.
5) Fix wrong listing of set reference counter, make counter
synchronous again, from Stefano Brivio.
6) Fix CIDR 0 in hash:net,port,net, from Eric Westbrook.
7) Fix allocation failure with large set, use kvcalloc().
From Andrey Ryabinin.
8) No need to disable BH when fetch ip set comment, patch from
Jozsef Kadlecsik.
9) Sanity check for valid sysfs entry in xt_IDLETIMER, from
Taehee Yoo.
10) Fix suspicious rcu usage via ip_set() macro at netlink dump,
from Jozsef Kadlecsik.
11) Fix setting default timeout via nfnetlink_cttimeout, this
comes with preparation patch to add nf_{tcp,udp,...}_pernet()
helper.
12) Allow ebtables table nat to be of filter type via nft_compat.
From Florian Westphal.
13) Incorrect calculation of next bucket in early_drop, do no bump
hash value, update bucket counter instead. From Vasily Khoruzhick.

For non-zero return from dumpit() we should break the loop
in rtnl_dump_all() and return the result. Otherwise, e.g.,
we could get the memory leak in inet6_dump_fib() [1]. The
pointer to the allocated struct fib6_walker there (saved
in cb->args) can be lost, reset on the next iteration.
Fix it by partially restoring the previous behavior before
commit c63586dc9b3e ("net: rtnl_dump_all needs to propagate
error from dumpit function"). The returned error from
dumpit() is still passed further.

Commit 5390a8df769e ("mtd: spi-nor: add support to non-uniform SFDP SPI
NOR flash memories") removed the 'nor->addr_width = 0;' statement when
spi_nor_parse_sfdp() returns an error, thus leaving ->addr_width in an
undefined state which can cause trouble when spi_nor_scan() checks its

On Stratix 10, the EMAC has 256 hash buckets for multicast filtering. This

Fix a MIPS `dma_alloc_coherent' regression from commit bc3ec75de545
("dma-mapping: merge direct and noncoherent ops") that causes a cached
allocation to be returned on noncoherent cache systems.
This is due to an inverted check now used in the MIPS implementation of
`arch_dma_alloc' on the result from `dma_direct_alloc_pages' before
doing the cached-to-uncached mapping of the allocation address obtained.
The mapping has to be done for a non-NULL rather than NULL result,
because a NULL result means the allocation has failed.
Invert the check for correct operation then.

The __no_sanitize_address_or_inline and __no_kasan_or_inline defines
are almost identical. The only difference is that __no_kasan_or_inline
does not have the 'notrace' attribute.
To be able to replace __no_sanitize_address_or_inline with the older
definition, add 'notrace' to __no_kasan_or_inline and change to two
users of __no_sanitize_address_or_inline in the s390 code.
The 'notrace' option is necessary for e.g. the __load_psw_mask function
in arch/s390/include/asm/processor.h. Without the option it is possible
to trace __load_psw_mask which leads to kernel stack overflow.

The "official" Condor boards have always been wired to mount NFS via
GEther, not EtherAVB -- the boards resoldered for EtherAVB were local
to Cogent Embedded, so we've been having an unpleasant situation where
a "normal" Condor board still can't mount NFS (unless an EtherAVB PHY
extension board is plugged in). Switch from EtherAVB to GEther at last!

The commit 37a3a98ef601 ("ALSA: hda - Enable runtime PM only for
discrete GPU") added a new ops gpu_bound to be called when GPU gets
bound. The patch overlooked, however, that vga_switcheroo_enable() is
called only once at GPU is bound. When an audio client is registered
after that point, it would miss the gpu_bound call. This leads to the
unexpected lack of runtime PM in HD-audio side.
For addressing that regression, just call gpu_bound callback manually
at vga_switcheroo_register_audio_client() when the GPU was already
bound.

I noticed during the creation of another bugfix that the BCH_CONST_PARAMS
option that is set by DOCG3 breaks setting variable parameters for any
other users of the BCH library code.
The only other user we have today is the MTD_NAND software BCH
implementation (most flash controllers use hardware BCH these days
and are not affected). I considered removing BCH_CONST_PARAMS entirely
because of the inherent conflict, but according to the description in
lib/bch.c there is a significant performance benefit in keeping it.
To avoid the immediate problem of the conflict between MTD_NAND_BCH
and DOCG3, this only sets the constant parameters if MTD_NAND_BCH
is disabled, which should fix the problem for all cases that
are affected. This should also work for all stable kernels.
Note that there is only one machine that actually seems to use the
DOCG3 driver (arch/arm/mach-pxa/mioa701.c), so most users should have
the driver disabled, but it almost certainly shows up if we wanted
to test random kernels on machines that use software BCH in MTD.
