There are a number of issues here:
* if trans->reduce_power_loaded is already true, we call
iwl_trans_set_reduce_power() with an uninitialized len
value
* in this case we also clobber a previous load/setting
* if iwl_uefi_get_reduced_power() returns an ERR_PTR() we
try to kfree() it
Move the iwl_trans_set_reduce_power() call into the success
case only to fix these issues.

If there's a rate->index that maps inside the range but
to an uninitialized value, then that's also a bad rate,
avoid printing "(nil)" in that case and rather print the
"BAD_RATE" string instead as in the else branch.

The setting of the 'sta' parameter is not needed. In the if-check that sets it

In FW restart scenarios, we allocate the queues from the
iwl_mvm_realloc_queues_after_restart() function, but that
is called before we insert the station ID into our map
(mvm->fw_id_to_mac_id).
However, in all cases where we're actually allocating a
queue for a "real" (not bcast, aux, ...) station we have
the sta pointer already, so just pass it along to use it
instead of looking it up.
This fixes an issue where after restart we only allocated
a queue of size 16 (due to the ordering issue described
above), and thus never got good throughput again since no
aggregates could be formed on transmit.

The ipw_fw_error structure contains a payload[] flexible array as well as
two pointers to this array area, ->elem, and ->log. The total size of the
allocated structure is computed without use of the <linux/overflow.h>
macros.
There's no reason to keep both a payload[] and an extra pointer to both the
elem and log members. Convert the elem pointer member into the flexible
array member, removing payload.
Fix the allocation of the ipw_fw_error structure to use size_add(),
struct_size(), and array_size() to compute the allocation. This ensures
that any overflow saturates at SIZE_MAX rather than overflowing and
potentially allowing an undersized allocation.
Before the structure change, the layout of ipw_fw_error was:
struct ipw_fw_error {
long unsigned int jiffies; /* 0 8 */
u32 status; /* 8 4 */
u32 config; /* 12 4 */
u32 elem_len; /* 16 4 */
u32 log_len; /* 20 4 */
struct ipw_error_elem * elem; /* 24 8 */
struct ipw_event * log; /* 32 8 */
u8 payload[]; /* 40 0 */
/* size: 40, cachelines: 1, members: 8 */
/* last cacheline: 40 bytes */
};
After this change, the layout is now:
struct ipw_fw_error {
long unsigned int jiffies; /* 0 8 */
u32 status; /* 8 4 */
u32 config; /* 12 4 */
u32 elem_len; /* 16 4 */
u32 log_len; /* 20 4 */
struct ipw_event * log; /* 24 8 */
struct ipw_error_elem elem[]; /* 32 0 */
/* size: 32, cachelines: 1, members: 7 */
/* last cacheline: 32 bytes */
};
This saves a total of 8 bytes for every ipw_fw_error allocation, and
removes the risk of a potential overflow on the allocation.

Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are
all special world-wide compatibility ccode-s. Most of these world-wide
ccode-s allow passive scan mode only for 2.4GHz channels 12-14,
only enabling them when an AP is seen on them.
Since linux-firmware has moved to the new cyfmac4356-pci.bin +

4356 devices using e.g. an X2 ccode fail to connect to an AP on

make versioncheck reports the following:
./drivers/net/ethernet/qlogic/qede/qede.h: 10 linux/version.h not needed.
./drivers/net/ethernet/qlogic/qede/qede_ethtool.c: 7 linux/version.h not needed.
So remove linux/version.h from both of these files. Also remove
linux/compiler.h while at it as it is also not being used.

The bindings for the am65-cpsw driver use the name "serdes" to refer to
the Serdes PHY. Thus, update the name used for the Serdes PHY within the
am65_cpsw_init_serdes_phy() function from "serdes-phy" to "serdes".

Update bindings to include Serdes PHY as an optional PHY, in addition to
the existing CPSW MAC's PHY. The CPSW MAC's PHY is required while the
Serdes PHY is optional. The Serdes PHY handle has to be provided only
when the Serdes is being configured in a Single-Link protocol. Using the
name "serdes-phy" to represent the Serdes PHY handle, the am65-cpsw-nuss
driver can obtain the Serdes PHY and request the Serdes to be
configured.
