[PATCH AUTOSEL 5.7 078/274] Bluetooth: btmtkuart: Improve exception handling in btmtuart_probe()

[Sasha Levin]

From: Chuhong Yuan <hslester96@gmail.com>

[ Upstream commit 4803c54ca24923a30664bea2a7772db6e7303c51 ]

Calls of the functions clk_disable_unprepare() and hci_free_dev()
were missing for the exception handling.
Thus add the missed function calls together with corresponding
jump targets.

[PATCH AUTOSEL 5.7 191/274] mt76: mt7615: do not always reset the dfs state setting the channel

[Sasha Levin]

From: Lorenzo Bianconi <lorenzo@kernel.org>

[ Upstream commit fdb786cce0ef3615dcbb30d8baf06a1d4cb7a344 ]

mac80211/hostapd runs mt7615_set_channel with the same channel
parameters sending multiple rdd commands overwriting the previous ones.
This behaviour is causing tpt issues on dfs channels.
Fix the issue checking new channel freq/width with the running one.

[PATCH AUTOSEL 5.7 201/274] net: dsa: mt7530: set CPU port to fallback mode

[Sasha Levin]

From: DENG Qingfang <dqfext@gmail.com>

[ Upstream commit 38152ea37d8bdaffa22603e0a5b5b86cfa8714c9 ]

Currently, setting a bridge's self PVID to other value and deleting
the default VID 1 renders untagged ports of that VLAN unable to talk to
the CPU port:

	bridge vlan add dev br0 vid 2 pvid untagged self
	bridge vlan del dev br0 vid 1 self
	bridge vlan add dev sw0p0 vid 2 pvid untagged
	bridge vlan del dev sw0p0 vid 1
	# br0 cannot send untagged frames out of sw0p0 anymore

That is because the CPU port is set to security mode and its PVID is
still 1, and untagged frames are dropped due to VLAN member violation.

Set the CPU port to fallback mode so untagged frames can pass through.
