All of the code in the probe path assumes ->sets != NULL and
->nrsets > 0. Error out if that's not the case to avoid dereferencing a
NULL pointer.

A report from Colin Ian King pointed a CoverityScan issue where error
values on these helpers where not checked in the drivers. These
helpers can error out only in case of a software bug in driver code,
not because of a runtime/hardware error. Hence, let's WARN_ON() in this
case and return 0 which is harmless anyway.

rtl8225se_rf_init() is never called in atomic context.
It calls mdelay() to busily wait, which is not necessary.
mdelay() can be replaced with msleep().
This patch only replaces the mdelay() that has >20ms time to wait.
This is found by a static analysis tool named DCNS written by myself.

When receiving a beacon or probe response, we should update the
boottime_ns field which is the timestamp the frame was received at.
(cf mac80211.h)
This fixes a scanning issue with Android since it relies on this
timestamp to determine when the AP has been seen for the last time
(via the nl80211 BSS_LAST_SEEN_BOOTTIME parameter).

Some features supported by firmware aren't advertised and there is no
way for a driver to query them. This includes e.g. monitor mode details.
Most firmwares support monitor interface but only the latest ones
/announce/ it with a "monitor" flag in the "cap" iovar. There isn't any
reliable detection method for older firmwares (BRCMF_C_MONITOR was tried
but "it only indicates the core part of the stack supports").
Similarly support for tagging monitor frames and building radiotap
headers can't be reliably detected for all firmwares.
This commit adds table that allows mapping features to firmware version.
It adds mappings for 43602a1 and 4366b1 firmwares from
linux-firmware.git. Both were confirmed to be passing monitor frames.

this, convert these variables to a set of bitops flags, to be

Driver must ensure that whenever it holds a pointer to the list
entry mwifiex_rx_reorder_tbl, it must protect the same with
rx_reorder_tbl_lock. At present there are many places where
driver does not ensure this. To cover all cases, spinlocks in
below funcions are moved out and made sure that the caller will
hold the spinlock:
mwifiex_11n_dispatch_pkt_until_start_win()
mwifiex_11n_scan_and_dispatch()

In order to support resin thru the pwrkey driver (they are very
similar in nature) we need to abstract the handling in this driver.
First we abstract pull_up_bit and status_bit along in driver data.
The event code sent for key events is quiried from DT.
Since the device can be child of pon lookup regmap and reg from
parent if lookup fails (we are child).

rcar_dmac_chan_get_residue() should not stop the DMAC, because
the commit 538603c6026c ("dmaengine: sh: rcar-dmac: avoid to write
CHCR.TE to 1 if TCR is set to 0") had fixed unexpected re-transferring
issue. But it had caused the next issue which might stop the cyclic
mode transferring. Thus, for example R-Car sound might be stopped
suddenly.
According to the commit 73a47bd0da66 ("dmaengine: rcar-dmac: use TCRB
instead of TCR for residue"), the purpose of clearing CHCR.DE bit is
flushing buffered data to calculate the exact residue.
Such the "exact" residue had been required by sh-sci driver. sh-sci
driver is calling dmaengine_pause() to stop transferring, and get
"exact" residue. Otherwise, it might receive extra data during
getting residue without pausing.
In rx_timer_fn() of sh-sci driver:
dmaengine_tx_status(); /* For checking roughly */
dmaengine_pause();
dmaengine_tx_status(); /* For getting residue */
dmaengine_terminate_all();
But, unfortunately the rcar-dmac driver didn't support dmaengine_pause()
at that time. So, the sh-sci driver cannot get the "exact" residue
without stopping the transferring, because rcar-dmac is buffering data
inside.
Because of these backgrounds, rcar-dmac had been cleared/set CHCR.DE
bit in rcar_dmac_chan_get_residue() to synchronizing data and getting
"exact" residue.
However, rcar-dmac driver has rcar_dmac_chan_pause() now, and clearing
CHCR.DE bit in rcar_dmac_chan_get_residue() doesn't need anymore.
So, this patch removes the rcar_dmac_sync_tcr().

A new driver got added that depends on QCOM_SMD and fails to link
as built-in with CONFIG_QCOM_SMD=m:
drivers/remoteproc/qcom_common.o: In function `smd_subdev_stop':
qcom_common.c:(.text+0x674): undefined reference to `qcom_smd_unregister_edge'
drivers/remoteproc/qcom_common.o: In function `smd_subdev_start':
qcom_common.c:(.text+0x700): undefined reference to `qcom_smd_register_edge'
We've fixed the same thing several times before, so use the same
dependency here.

Unwind the modified table_ptr and restore it to the local copy
upon any subsequent failures in the rproc_start() function. This
keeps the function to remain balanced on failures without the need
to balance any modified variables elsewhere.
While at this, do some minor cleanup of the extra lines between
the failure labels as well.

The commit 4f1acd758b08 ("hwspinlock: Add devm_xxx() APIs to request/free
hwlock") introduces one bug, that will return one error pointer if failed
to request one hwlock, but we expect NULL pointer on error for consumers.
This patch will fix this issue.

The cxgbit driver expects that __iscsit_free_cmd() is called before the
target core frees the command page list. Since this patch breaks the
cxgbit driver, revert it.

Instead of doing strdup and kstrto* just use match_int for dev params.
It will be ok to use int instead of unsigned long in tcmu_set_dev_attrib
because that is only being used for max sectors and block size and the
supported values for them are well under the max possible integer value.
