Currently we are trying to enable/disable the clk of irq's gpio bank when
unmask/mask irq. But the kernel's "lazy disable approach" will skip masking
irq when the irq chip doesn't support irq_disable ops.
So we may hit this case:
irq_enable-> enable clk
irq_disable-> noop
irq_enable-> enable clk again
irq_disable-> noop

[ Upstream commit 639b08810d ]
When accessing Xenstore in a transaction the user is specifying a
transaction id which he normally obtained from Xenstore when starting
the transaction. Xenstore is validating a transaction id against all
known transaction ids of the connection the request came in. As all
requests of a domain not being the one where Xenstore lives share
one connection, validation of transaction ids of different users of
Xenstore in that domain should be done by the kernel of that domain
being the multiplexer between the Xenstore users in that domain and
Xenstore.
In order to prohibit one Xenstore user "hijacking" a transaction from
another user the xenbus driver has to verify a given transaction id
against all known transaction ids of the user before forwarding it to
Xenstore.

[ Upstream commit 88407beb1b ]
Ath10k reports the phy capability that supports P2P_DEVICE interface.
When we use the P2P supported wpa_supplicant to start connection, it'll
create two interfaces, one is wlan0 (vdev_id=0) and one is P2P_DEVICE
p2p-dev-wlan0 which is for p2p control channel (vdev_id=1).
ath10k_pci mac vdev create 0 (add interface) type 2 subtype 0
ath10k_add_interface: vdev_id: 0, txpower: 0, bss_power: 0
...
ath10k_pci mac vdev create 1 (add interface) type 2 subtype 1
ath10k_add_interface: vdev_id: 1, txpower: 0, bss_power: 0
And the txpower in per vif bss_conf will only be set to valid tx power when
the interface is assigned with channel_ctx.
But this P2P_DEVICE interface will never be used for any connection, so
that the uninitialized bss_conf.txpower=0 is assinged to the
arvif->txpower when interface created.
Since the txpower configuration is firmware per physical interface.
So the smallest txpower of all vifs will be the one limit the tx power
of the physical device, that causing the low txpower issue on other
active interfaces.
wlan0: Limiting TX power to 21 (24 - 3) dBm
ath10k_pci mac vdev_id 0 txpower 21
ath10k_mac_txpower_recalc: vdev_id: 1, txpower: 0
ath10k_mac_txpower_recalc: vdev_id: 0, txpower: 21
ath10k_pci mac txpower 0
This issue only happens when we use the wpa_supplicant that supports
P2P or if we use the iw tool to create the control P2P_DEVICE interface.
