The GSWIP switch is a platform device, so the initial set of constraints
that I thought would cause this (I2C or SPI buses which call ->remove on
->shutdown) do not apply. But there is one more which applies here.
If the DSA master itself is on a bus that calls ->remove from ->shutdown
(like dpaa2-eth, which is on the fsl-mc bus), there is a device link
between the switch and the DSA master, and device_links_unbind_consumers()
will unbind the GSWIP switch driver on shutdown.
So the same treatment must be applied to all DSA switch drivers, which
is: either use devres for both the mdiobus allocation and registration,
or don't use devres at all.
The gswip driver has the code structure in place for orderly mdiobus
removal, so just replace devm_mdiobus_alloc() with the non-devres
variant, and add manual free where necessary, to ensure that we don't
let devres free a still-registered bus.

Nobody in this driver calls mdiobus_unregister(), which is necessary if
mdiobus_register() completes successfully. So if the devres callbacks
that free the mdiobus get invoked (this is the case when unbinding the
driver), mdiobus_free() will BUG if the mdiobus is still registered,
which it is.
My speculation is that this is due to the fact that prior to commit
ac3a68d56651 ("net: phy: don't abuse devres in devm_mdiobus_register()")
from June 2020, _devm_mdiobus_free() used to call mdiobus_unregister().
But at the time that the mt7530 support was introduced in May 2021, the
API was already changed. It's therefore likely that the blamed patch was
developed on an older tree, and incorrectly adapted to net-next. This
makes the Fixes: tag correct.
Fix the problem by using the devres variant of mdiobus_register.

mdiobus_free() will panic when called from devm_mdiobus_free() <-

The Seville VSC9959 switch is a platform device, so the initial set of
constraints that I thought would cause this (I2C or SPI buses which call
->remove on ->shutdown) do not apply. But there is one more which
applies here.
If the DSA master itself is on a bus that calls ->remove from ->shutdown
(like dpaa2-eth, which is on the fsl-mc bus), there is a device link
between the switch and the DSA master, and device_links_unbind_consumers()
will unbind the seville switch driver on shutdown.
So the same treatment must be applied to all DSA switch drivers, which
is: either use devres for both the mdiobus allocation and registration,
or don't use devres at all.
The seville driver has a code structure that could accommodate both the
mdiobus_unregister and mdiobus_free calls, but it has an external
dependency upon mscc_miim_setup() from mdio-mscc-miim.c, which calls
devm_mdiobus_alloc_size() on its behalf. So rather than restructuring
that, and exporting yet one more symbol mscc_miim_teardown(), let's work
with devres and replace of_mdiobus_register with the devres variant.
When we use all-devres, we can ensure that devres doesn't free a
still-registered bus (it either runs both callbacks, or none).

When 803.2ad mode enables a participating port, it should update
the slave-array. I have observed that the member links are participating
and are part of the active aggregator while the traffic is egressing via
only one member link (in a case where two links are participating). Via
kprobes I discovered that slave-arr has only one link added while
the other participating link wasn't part of the slave-arr.
I couldn't see what caused that situation but the simple code-walk
through provided me hints that the enable_port wasn't always associated
with the slave-array update.

Mayuresh reported commit 20802d8d477d ("riscv: extable: add a dedicated
uaccess handler") breaks the writev02 test case in LTP. This is due to
the err reg isn't correctly set with the errno(-EFAULT in writev02
case). First of all, the err and zero regs are reg numbers rather than
reg offsets in struct pt_regs; Secondly, regs_set_gpr() should write
the regs when offset isn't zero(zero means epc)
Fix it by correcting regs_set_gpr() logic and passing the correct reg
offset to it.

The kernel parameter "tp_printk_stop_on_boot" starts with "tp_printk" which is
the same as another kernel parameter "tp_printk". If "tp_printk" setup is
called before the "tp_printk_stop_on_boot", it will override the latter
and keep it from being set.
This is similar to other kernel parameter issues, such as:
Commit 745a600cf1a6 ("um: console: Ignore console= option")
or init/do_mounts.c:45 (setup function of "ro" kernel param)
Fix it by checking for a "_" right after the "tp_printk" and if that
exists do not process the parameter.

Commit 7707f7227f09 ("drm/rockchip: Add support for afbc") switched up
the rk3399_vop_big[] register windows, but it did so incorrectly.
The biggest problem is in rk3288_win23_data[] vs.
rk3368_win23_data[] .format field:
RK3288's format: VOP_REG(RK3288_WIN2_CTRL0, 0x7, 1)
RK3368's format: VOP_REG(RK3368_WIN2_CTRL0, 0x3, 5)
Bits 5:6 (i.e., shift 5, mask 0x3) are correct for RK3399, according to
the TRM.
There are a few other small differences between the 3288 and 3368
definitions that were swapped in commit 7707f7227f09. I reviewed them to
the best of my ability according to the RK3399 TRM and fixed them up.
This fixes IOMMU issues (and display errors) when testing with BG24
color formats.

rtla osnoise and timerlat are causing a segmentation fault when running
with the --trace option on a kernel that does not support multiple
instances. For example:
[root@f34 rtla]# rtla osnoise top -t
failed to enable the tracer osnoise
Could not enable osnoiser tracer for tracing
Failed to enable the trace instance
Segmentation fault (core dumped)
This error happens because the exit code of the tools is trying
to destroy the trace instance that failed to be created.
Make osnoise_destroy_tool() aware of possible NULL osnoise_tool *,
and do not attempt to destroy it. This also simplifies the exit code.

For some long forgotten reason, the nfs_client cl_flags field is
initialised in nfs_get_client() instead of being initialised at
allocation time. This quirk was harmless until we moved the call to
nfs_create_rpc_client().

Ever since Tomi extracted the core code in 2014 it's been defacto me
maintaining this, with help from others from dri-devel and sometimes
Linus (but those are mostly merge conflicts):
$ git shortlog -ns drivers/video/fbdev/core/ | head -n5
35 Daniel Vetter
23 Linus Torvalds
10 Hans de Goede
9 Dave Airlie
6 Peter Rosin
I think ideally we'd also record that the various firmware fb drivers
(efifb, vesafb, ...) are also maintained in drm-misc because for the
past few years the patches have either been to fix handover issues
with drm drivers, or caused handover issues with drm drivers. So any
other tree just doesn't make sense. But also, there's plenty of
outdated MAINTAINER entries for these with people and git trees that
haven't been active in years, so maybe let's just leave them alone.
And furthermore distros are now adopting simpledrm as the firmware fb
driver, so hopefully the need to care about the fbdev firmware drivers
will go down going forward.
Note that drm-misc is group maintained, I expect that to continue like
we've done before, so no new expectations that patches all go through
my hands. That would be silly. This also means I'm happy to put any
other volunteer's name in the M: line, but otherwise git log says I'm
the one who's stuck with this.

The check done by regulator_late_cleanup() to detect whether a regulator
is on was inconsistent with the check done by _regulator_is_enabled().
While _regulator_is_enabled() takes the enable GPIO into account,
regulator_late_cleanup() was not doing that.
This resulted in a false positive, e.g. when a GPIO-controlled fixed
regulator was used, which was not enabled at boot time, e.g.
reg_disp_1v2: reg_disp_1v2 {
compatible = "regulator-fixed";
regulator-name = "display_1v2";
regulator-min-microvolt = <1200000>;
regulator-max-microvolt = <1200000>;
gpio = <&tlmm 148 0>;
enable-active-high;
};
Such regulator doesn't have an is_enabled() operation. Nevertheless
it's state can be determined based on the enable GPIO. The check in
regulator_late_cleanup() wrongly assumed that the regulator is on and
tried to disable it.

With CPU re-ordering on write instructions, there might
be a chance that the HWO is set before the TRB is updated
with the new mapped buffer address.
And in the case where core is processing a list of TRBs
it is possible that it fetched the TRBs when the HWO is set
but before the buffer address is updated.
Prevent this by adding a memory barrier before the HWO
is updated to ensure that the core always process the
updated TRBs.

Setting the output of a GPIO to 1 using gpiod_set_value(), followed by
reading the same GPIO using gpiod_get_value(), will currently yield an
incorrect result.
This is because the SiFive GPIO device stores the output values in reg_set,
not reg_dat.
Supply the flag BGPIOF_READ_OUTPUT_REG_SET to bgpio_init() so that the
generic driver reads the correct register.

Messages around firmware download were incorrectly tagged as being related
to discovery trace events. Thus, firmware download status ended up dumping
the trace log as well as the firmware update message. As there were a
couple of log messages in this state, the trace log was dumped multiple
times.
Resolve this by converting from trace events to SLI events.
