These helper functions seems useless. And in some cases
we want to use test_and_[set/clear]_bit, these helpers
will make the code more complicated. So remove them.

kmemdup is introduced to duplicate a region of memory in a neat way.
Rather than kmalloc/kzalloc + memcpy, which the programmer needs to
write the size twice (sometimes lead to mistakes), kmemdup improves
readability, leads to smaller code and also reduce the chances of mistakes.
Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy.

xennet_fill_frags() uses ~0U as return value when the sk_buff is not able
to cache extra fragments. This is incorrect because the return type of
xennet_fill_frags() is RING_IDX and 0xffffffff is an expected value for
ring buffer index.
In the situation when the rsp_cons is approaching 0xffffffff, the return
value of xennet_fill_frags() may become 0xffffffff which xennet_poll() (the
caller) would regard as error. As a result, queue->rx.rsp_cons is set
incorrectly because it is updated only when there is error. If there is no
error, xennet_poll() would be responsible to update queue->rx.rsp_cons.
Finally, queue->rx.rsp_cons would point to the rx ring buffer entries whose
queue->rx_skbs[i] and queue->grant_rx_ref[i] are already cleared to NULL.
This leads to NULL pointer access in the next iteration to process rx ring
buffer entries.
The symptom is similar to the one fixed in
commit 00b368502d18 ("xen-netfront: do not assume sk_buff_head list is
empty in error handling").
This patch changes the return type of xennet_fill_frags() to indicate
whether it is successful or failed. The queue->rx.rsp_cons will be
always updated inside this function.

The driver was working with fixed phy without any noticeable issues. This bug

Commit b6b6cc9acd7b, changed the call to dwxgmac2_rss_write_reg()
passing it the variable cfg->key[i].
As key is an u8 but we write 32 bits at a time we need to cast it into
an u32 so that the correct key values are written. Notice that the for
loop already takes this into account so we don't try to write past the
keys size.

commit 174e23810cd31
("sk_buff: drop all skb extensions on free and skb scrubbing") made napi
recycle always drop skb extensions. The additional skb_ext_del() that is
performed via nf_reset on napi skb recycle is not needed anymore.
Most nf_reset() calls in the stack are there so queued skb won't block
'rmmod nf_conntrack' indefinitely.
This removes the skb_ext_del from nf_reset, and renames it to a more
fitting nf_reset_ct().
In a few selected places, add a call to skb_ext_reset to make sure that
no active extensions remain.
I am submitting this for "net", because we're still early in the release
cycle. The patch applies to net-next too, but I think the rename causes
needless divergence between those trees.

Currently, data variable in ar9003_hw_thermo_cal_apply() could be
uninitialized if ar9300_otp_read_word() will fail to read the value.
Initialize data variable with 0 to prevent an undefined behavior. This
will be enough to handle error case when ar9300_otp_read_word() fails.

Since ath10k_mac_tx_push_txq() can be called from process context, we
must explicitly disable softirqs before the call into mac80211.
By calling ieee80211_tx_dequeue_ni() instead of ieee80211_tx_dequeue()
we make sure softirqs are always disabled even in the case when
ath10k_mac_tx_push_txq() is called from process context.
Calling ieee80211_tx_dequeue_ni() with softirq's already disabled
(e.g., from softirq context) should be safe as the local_bh_disable()
and local_bh_enable() functions (called from ieee80211_tx_dequeue_ni)
are fully reentrant.

brcmfmac assumed the wifi device always remains powered on and thus
hardcoded the MMC_PM_KEEP_POWER flag expecting the wifi device to
remain on even during suspend/resume cycles.
This is not always the case, some appliances cut power to everything
connected via SDIO for efficiency reasons and this leads to wifi not
being usable after coming out of suspend because the device was not
correctly reinitialized.
So we check for the keep_power capability and if it's not present then
we remove the device and probe it again during resume to mirror what's
happening in hardware and ensure correct reinitialization in the case
when MMC_PM_KEEP_POWER is not supported.
