eaa4e501cf staging: wlan-ng: remove unnecessary casts from prism2usb.c
usb_get_intfdata returns a void pointer. It is not necessary to
explicitly cast to the desired type and removing the casts is
consistent with most use of usb_get_intfdata.

48d357f0be staging: rtl8188eu: reduce indentation level in rtw_alloc_stainfo
Remove else-arm from if-else statement. Move the else code out of the
if-else and skip it by adding goto exit to the if block. The exit label
was directly after the else-arm, so there is no change in behaviour.
Reduces indentation level and clears a line over 80 characters

8008d9e7dd staging: wfx: fix CONFIG_MMC=m with CONFIG_WFX=y
If CONFIG_MMC=m and CONFIG_WFX=y, compilation complains with undefined
references:

    drivers/staging/wfx/main.o: In function `wfx_core_init': /linux/drivers/staging/wfx/main.c:488: undefined reference to `sdio_register_driver'
    drivers/staging/wfx/main.o: In function `wfx_core_exit': /linux/drivers/staging/wfx/main.c:496: undefined reference to `sdio_unregister_driver'
    drivers/staging/wfx/main.o:(.debug_addr+0x1a8): undefined reference to `sdio_register_driver'
    drivers/staging/wfx/main.o:(.debug_addr+0x6f0): undefined reference to `sdio_unregister_driver'

Indeed, symbols sdio_* are not present in kernel image.

This patch disallows CONFIG_WFX=y if CONFIG_MMC=m.

This solution impacts users who want to use SPI bus with configuration:
CONFIG_WFX=y + CONFIG_SPI=y + CONFIG_MMC=m. However, I think this is a
twisted case. So, I think it won't be missed.

a374ba3dc8 staging: wfx: relocate wfx_fill_sl_key() in secure_link.h
"Secure link" feature is not available in in-tree driver (because it
depends on mbedtls). Thus, secure_link.h only empty functions.

Module parameter "slk_key" and associated function wfx_fill_sl_key() had
an unjustifiable place in main.c. This patch relocate them to
secure_link.h.

BTW, content of wfx_fill_sl_key() is now useless. Just keep a warning if
user try to use "slk_key" attribute (unsupported by this driver).

cf1b2326b7 nbd: verify socket is supported during setup
nbd requires socket families to support the shutdown method so the nbd
recv workqueue can be woken up from its sock_recvmsg call. If the socket
does not support the callout we will leave recv works running or get hangs
later when the device or module is removed.

This adds a check during socket connection/reconnection to make sure the
socket being passed in supports the needed callout.

962399bb7f ata: libahci_platform: Fix regulator_get_optional() misuse
This driver is using regulator_get_optional() to handle all the supplies
that it handles, and only ever enables and disables all supplies en masse
without ever doing any other configuration of the device to handle missing
power. These are clear signs that the API is being misused - it should only
be used for supplies that may be physically absent from the system and in
these cases the hardware usually needs different configuration if the
supply is missing. Instead use normal regualtor_get(), if the supply is
not described in DT then the framework will substitute a dummy regulator in
so no special handling is needed by the consumer driver.

In the case of the PHY regulator the handling in the driver is a hack to
deal with integrated PHYs; the supplies are only optional in the sense
that that there's some confusion in the code about where they're bound to.
From a code point of view they function exactly as normal supplies so can
be treated as such. It'd probably be better to model this by instantiating
a PHY object for integrated PHYs.

This was preceded by us timing out everything and shutting down the
sockets for the device.  The problem is we had a request in the queue at
the same time, so we completed the request twice.  This can actually
happen in a lot of cases, we fail to get a ref on our config, we only
have one connection and just error out the command, etc.

Fix this by checking cmd->status in nbd_read_stat.  We only change this
under the cmd->lock, so we are safe to check this here and see if we've
already error'ed this command out, which would indicate that we've
completed it as well.

de6346ecbc nbd: protect cmd->status with cmd->lock
We already do this for the most part, except in timeout and clear_req.
For the timeout case we take the lock after we grab a ref on the config,
but that isn't really necessary because we're safe to touch the cmd at
this point, so just move the order around.

For the clear_req cause this is initiated by the user, so again is safe.

2b2ed9750f io_uring: fix bad inflight accounting for SETUP_IOPOLL|SETUP_SQTHREAD
We currently assume that submissions from the sqthread are successful,
and if IO polling is enabled, we use that value for knowing how many
completions to look for. But if we overflowed the CQ ring or some
requests simply got errored and already completed, they won't be
available for polling.

For the case of IO polling and SQTHREAD usage, look at the pending
poll list. If it ever hits empty then we know that we don't have
anymore pollable requests inflight. For that case, simply reset
the inflight count to zero.

498ccd9eda io_uring: used cached copies of sq->dropped and cq->overflow
We currently use the ring values directly, but that can lead to issues
if the application is malicious and changes these values on our behalf.
Created in-kernel cached versions of them, and just overwrite the user
side when we update them. This is similar to how we treat the sq/cq
ring tail/head updates.

935d1e4590 io_uring: Fix race for sqes with userspace
io_ring_submit() finalises with
1. io_commit_sqring(), which releases sqes to the userspace
2. Then calls to io_queue_link_head(), accessing released head's sqe

Reorder them.

fb5ccc9878 io_uring: Fix broken links with offloading
io_sq_thread() processes sqes by 8 without considering links. As a
result, links will be randomely subdivided.

The easiest way to fix it is to call io_get_sqring() inside
io_submit_sqes() as do io_ring_submit().

Downsides:
1. This removes optimisation of not grabbing mm_struct for fixed files
2. It submitting all sqes in one go, without finer-grained sheduling
with cq processing.
