sg_ioctl() support to enable blktrace, which will create debugfs entries
"/sys/kernel/debug/block/sgx/", however, there is no guarantee that user
will remove these entries through ioctl, and deleting sg device doesn't
cleanup these blktrace entries.
This problem can be fixed by cleanup blktrace while releasing
request_queue, however, it's not a good idea to do this special handling
in common layer just for sg device.
Fix this problem by shutdown bltkrace in sg_device_destroy(), where the
device is deleted and all the users close the device, also grab a
scsi_device reference from sg_add_device() to prevent scsi_device to be
freed before sg_device_destroy();

Klocwork reported warning of NULL pointer may be dereferenced. The routine
exits when sa_ctl is NULL and fcport is allocated after the exit call thus
causing NULL fcport pointer to dereference at the time of exit.
To avoid fcport pointer dereference, exit the routine when sa_ctl is NULL.

In the error exits in target_setup_session(), if a branch is taken to
free_sess: transport_free_session() may call to target_free_cmd_counter()
and then fall through to call target_free_cmd_counter() a second time.
This can, and does, sometimes cause seg faults since the data field in
cmd_cnt->refcnt has been freed in the first call.
Fix this problem by simply returning after the call to
transport_free_session(). The second call is redundant for those cases.

Hyper-V synthetic SCSI devices do not support the MAINTENANCE_IN SCSI
command, so scsi_report_opcode() always fails, resulting in messages like
this:
hv_storvsc <guid>: tag#205 cmd 0xa3 status: scsi 0x2 srb 0x86 hv 0xc0000001
The recently added support for command duration limits calls
scsi_report_opcode() four times as each device comes online, which
significantly increases the number of messages logged in a system with many
disks.
Fix the problem by always marking Hyper-V synthetic SCSI devices as not
supporting scsi_report_opcode(). With this setting, the MAINTENANCE_IN SCSI
command is not issued and no messages are logged.

Fix the I/O hang that arises because of the MSIx vector not having a mapped
online CPU upon receiving completion.
SCSI cmds take the blk_mq route, which is setup during init. Reserved cmds
fetch the vector_no from mq_map after init is complete. Before init, they
have to use 0 - as per the norm.

sparse points out an embarrasing bug in an older patch of mine,
which uses the register offset instead of an __iomem pointer:
drivers/clk/pxa/clk-pxa3xx.c:167:9: sparse: sparse: Using plain integer as NULL pointer

The sprd_div_helper_round_rate() function calls divider_round_rate()
which calls divider_round_rate_parent() which calls
divider_determine_rate(). This call chain converts back and forth from
the rate request structure to make a determine_rate clk_op fit with a
round_rate clk_op. Simplify the code here by directly calling
divider_determine_rate() instead.
This fixes a smatch warning where an unsigned long is compared to less
than zero, which is impossible. This makes sprd_div_helper_round_rate()
unnecessary as well so simply remove it and fold it into the only caller
left.

Merge series from Mark Brown <broonie@kernel.org>:
Since Takashi found an issue with maple tree syncing registers it
shouldn't do add some test cases that catch that case and some more
potential issues, ideally we'd run through the combination of
readability with all possible I/O calls but that's lifting for another
day. We did find one issue with missing readability checks which will
be fixed separately.

A recent patch replaced a tasklet execution of cq->comp_handler by a
direct call. While this made sense it let changes to cq->notify state be
unprotected and assumed that the cq completion machinery and the ulp done
callbacks were reentrant. The result is that in some cases completion
events can be lost. This patch moves the cq->comp_handler call inside of
the spinlock in rxe_cq_post which solves both issues. This is compatible
with the matching code in the request notify verb.
Fixes: 78b26a335310 ("RDMA/rxe: Remove tasklet call from rxe_cq.c")

secondary sequencer
The select_fifo/dma_mode() functions in geni driver enable/disable
interrupts (secondary included) conditionally for non-uart modes, while
uart is supposed to manage this internally.
However, only uart uses secondary IRQs while spi, i2c do not care about
these at all making their enablement (or disablement) totally unnecessary
for these protos.
Similarly, select_gpi_mode() also does disable s_irq and its useless again.
Drop enabling/disabling secondary IRQs.
This doesn't solve any observed problem but only gets rid of code pieces
that are not required.

Some of the regulators on the MT6358/MT6366 PMICs have just one linear
voltage range. These are the bulk regulators and VSRAM_* LDOs. Currently
they are modeled with one linear range, but also have their minimum,
maximum, and step voltage described.
Convert them to the linear voltage helpers. These helpers are a bit
simpler, and we can also drop the linear range definitions. Also reflow
the touched lines now that they are shorter.

In the MT6358 regulator driver, each regulator is described by a
|struct regulator_desc| wrapped by a |struct mt6358_regulator_info|.
The latter was tied to the regulator device using the config's
driver_data field, which meant that the variables could not be constant.
Since each regulator device has a pointer to its regulator_desc, and
mt6358_regulator_info wraps that, the driver could use container_of()
to retrieve it instead.
Switch to using container_of(), drop tha driver_data setting, and
const-ify all the regulator descriptions.

The *_SSHUB regulators are actually alternate configuration interfaces
for their non *_SSHUB counterparts. They are not separate regulator
outputs. These registers are intended for the companion processor to
use to configure the power rails while the main processor is sleeping.
They are not intended for the main operating system to use.
Since they are not real outputs they shouldn't be modeled separately.
Remove them. Luckily no device tree actually uses them.

The VCN33_BT and VCN33_WIFI regulators are actually the same regulator,
having the same voltage setting and output pin. There are simply two
enable bits that are ORed together to enable the regulator.
Having two regulators representing the same output pin is misleading
from a design matching standpoint, and also error-prone in driver
implementations. If consumers try to set different voltages on either
regulator, the one set later would override the one set before. There
are ways around this, such as chaining them together and having the
downstream one act as a switch. But given there's only one output pin,
such a workaround doesn't match reality.
Remove the VCN33_WIFI regulator. During the probe phase, have the driver
sync the enable status of VCN33_WIFI to VCN33_BT. Also drop the suffix
so that the regulator name matches the pin name in the datasheet.

mlxsw will need to keep track of certain devices that are not related to
any of its front panel ports. This includes IPIP netdevices. To be able to
query the list of supported IPIP types, router->ipip_ops_arr needs to be

To that end, move the IPIP initialization up (and finalization
correspondingly down).

RIF configuration contains a number of parameters that cannot be changed
after the RIF is created. For the IPIP loopbacks, this is currently worked
around by creating a new RIF with the desired configuration changes
applied, and updating next hops to the new RIF, and then destroying the old
RIF. This operation will be useful as a reusable atom, so extract a helper
to that effect.

This function will be useful later as the driver will need to retroactively
create RIFs for new uppers with addresses.
Add another helper that assumes RCU lock, and restructure the code to
skip the IPv6 branch not through conditioning on the addr_list_empty
variable, but by directly returning the result value. This makes the skip
more obvious than it previously was.
