ath10k: re-enable interrupts properly in hw recovery
Recent changes done to start/restart sequences
broke hw recovery in some hw configurations. The
pci transport was stopped twice however due to a
workaround in the pci disabling code the
disable/enable for first msi interrupt was not
balanced. This ended up with irqs not being
properly re-enabled and the following print out
during recovery:
ath10k: failed to receive control response completion, polling..
ath10k: Service connect timeout: -110
ath10k: Could not init core: -110
Legacy interrupt mode was unaffected while msi
ranged mode would be partially crippled (it would
miss fw indication interrupts but otherwise it
worked fine).
This fixes completely broken fw recovery for a
single msi interrupt mode and fixes subsequent fw
crash reports for msi range interrupt mode.

carl9170: tx: Replace rcu_assign_pointer() with RCU_INIT_POINTER()
According to RCU_INIT_POINTER()'s block comment 3.a, it can be used if
"3. The referenced data structure has already been exposed to readers either
at compile time or via rcu_assign_pointer() -and-
a. You have not made -any- reader-visible changes to this structure since
then".
This case fulfills the conditions above because between the rcu_dereference()
call (cvif = rcu_dereference(ar->beacon_iter);) and the rcu_assign_pointer()
call there is no update of the "cvif" variable.
Therefore, this patch makes the replacement.
The following Coccinelle semantic patch was used:
@@
identifier v;
@@
v = rcu_dereference(...);
... when != rcu_dereference(...);
when != v = ...;
when != (<+...v...+>)++;
when != \(memcpy\|memset\)(...);
(
- rcu_assign_pointer
+ RCU_INIT_POINTER
(..., v);
|
if(...) {
... when != v = ...;
- rcu_assign_pointer
+ RCU_INIT_POINTER
(..., v);
... when any
}
)
Because there are cases where between a “rcu_dereference()” call and a
“rcu_assign_pointer()” call might be updates of the value that interests us,
the Coccinelle semantic patch ignores them and replaces with
"RCU_INIT_POINTER()" only when the update is not happening.

wil6210: fix free'd memory access in wil_if_free()
In the wil_priv_deinit(), wdev->netdev is accessed, so free_netdev()
should not be called before mentioned call.
Set wdev->netdev to NULL Make sure no more attempts to use it.
It is used for debug printk if not NULL.
This fix kernel panic on module unload and in case error on probe;
if memory allocation debugging enabled.
