Before this change when a bond in mode 2 lost link, all of its slaves
lost link, the bonding device would never recover even after the
expiration of updelay. This change removes the updelay when the bond
currently has no usable links. Conforming to bonding.txt section 13.1
paragraph 4.
Fixes: 41f891004063 ("bonding: ignore updelay param when there is no active slave")

For bus-based driver, device removal is implemented as:
1 device_remove()->
2 bus->remove()->
3 driver->remove()
Driver core needs no inform from callee(bus driver) about the
result of remove callback. In that case, commit fc7a6209d571
("bus: Make remove callback return void") forces bus_type::remove
be void-returned.
Now we have the situation that both 1 & 2 of calling chain are
void-returned, so it does not make much sense for 3(driver->remove)
to return non-void to its caller.
So the basic idea behind this change is making remove() callback of
any bus-based driver to be void-returned.
This change, for itself, is for device drivers based on acpi-bus.

Resets may occur with or without user interaction. For example, a TX hang
or reconfiguration of parameters will result in a reset. During reset, the
VSI is freed, freeing any statistics structures inside as well. This would
create an issue for the user where a reset happens in the background,
statistics set to zero, and the user checks ring statistics expecting them
to be populated.
To ensure this doesn't happen, accumulate ring statistics over reset.
Define a new ring statistics structure, ice_ring_stats. The new structure
lives in the VSI's parent, preserving ring statistics when VSI is freed.
1. Define a new structure vsi_ring_stats in the PF scope
2. Allocate/free stats only during probe, unload, or change in ring size
3. Replace previous ring statistics functionality with new structure

During reset, hardware and software statistics were set to zero. This

The driver is currently using ICE_LINK_SPEED_* defines that mirror what
ethtool.h defines, with one exception ICE_LINK_SPEED_UNKNOWN.
This issue is fixed by the following changes:
1. replace ICE_LINK_SPEED_UNKNOWN with 0 because SPEED_UNKNOWN in
ethtool.h is "-1" and that doesn't match the driver's expected behavior
2. transform ICE_LINK_SPEED_*MBPS to SPEED_* using static tables and
fls()-1 to convert from BIT() to an index in a table.

In e100_xmit_prepare(), if we can't map the skb, then return -ENOMEM, so
e100_xmit_frame() will return NETDEV_TX_BUSY and the upper layer will
resend the skb. But the skb is already freed, which will cause UAF bug
when the upper layer resends the skb.

A problem about modprobe fm10k failed is triggered with the following log
given:
Intel(R) Ethernet Switch Host Interface Driver

The reason is that fm10k_init_module() returns fm10k_register_pci_driver()
directly without checking its return value, if fm10k_register_pci_driver()
failed, it returns without removing debugfs and destroy workqueue,
resulting the debugfs of fm10k can never be created later and leaks the

There is no reason that I can see why the no-op tagging protocol should
be registered manually, so make it a module and make all drivers which
have any sort of reference to DSA_TAG_PROTO_NONE select it.
Note that I don't know if ksz_get_tag_protocol() really needs this,
or if it's just the logic which is poorly written. All switches seem to
have their own tagging protocol, and DSA_TAG_PROTO_NONE is just a
fallback that never gets used.

When fail to dma_map_single() in mtk_rx_alloc(), it returns directly.
But the memory allocated for local variable data is not freed, and
local variabel data has not been attached to ring->data[i] yet, so the
memory allocated for local variable data will not be freed outside
mtk_rx_alloc() too. Thus memory leak would occur in this scenario.

Zero-length arrays are deprecated[1] and are being replaced with
flexible array members in support of the ongoing efforts to tighten the
FORTIFY_SOURCE routines on memcpy(), correctly instrument array indexing
with UBSAN_BOUNDS, and to globally enable -fstrict-flex-arrays=3.
Replace zero-length array with flexible-array member.
This results in no differences in binary output (most especially because
struct pda_antenna_gain is unused). The struct is kept for future
reference.

During doing change_interface(), hardware is power-off, so some components
are inaccessible and return error. This causes things unexpected, and we
don't have a warning message for that. So, ignore some IO operations in
this situation, and add a warning message to indicate something wrong.

There are some registers for transmit waveform control, two of them used
in this change are for BANDEDGE and TX_SHAPE control. BANDEDGE controls
whether to apply band edge filter to transmit waveform. TX_SHAPE controls
whether to apply triangular mask to transmit waveform. It is found for
some chip, these two should be turned off during OFDMA UL traffic for
better performance.

Add macro to get FD(frequency domain) CFO field from ie_type 1, and correct
the naming for preamble CFO field. Each IC could assign the CFO source to
either FD CFO or preamble CFO in chip_info. Based on the suggestion from HW
designer, rtw8852b and its derived versions will have better CFO tracking
performance with FD CFO.

it should keep original TX power from regular predefined tables, so

Prefer struct_size() over open-coded versions of idiom:
sizeof(struct-with-flex-array) + sizeof(typeof-flex-array-elements) * count
where count is the max number of items the flexible array is supposed to
contain.
In this particular case, in the open-coded version sizeof(typeof-flex-array-elements)
is implicit in _count_ because the type of the flex array data is u8:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/fwil_types.h:941:
941 struct brcmf_dload_data_le {
942 __le16 flag;
943 __le16 dload_type;
944 __le32 len;
945 __le32 crc;
946 u8 data[];
947 };

struct brcmf_dload_data_le
One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in struct brcmf_dload_data_le.
Important to mention is that doing a build before/after this patch results
in no binary output differences.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines
on memcpy() and help us make progress towards globally enabling
-fstrict-flex-arrays=3 [1].
