[PATCH AUTOSEL 5.4 1/5] selftests: tls: use exact comparison in recv_partial

[Sasha Levin]

From: Jakub Kicinski <kuba@kernel.org>

[ Upstream commit 49d821064c44cb5ffdf272905236012ea9ce50e3 ]

This exact case was fail for async crypto and we weren't
catching it.

[PATCH AUTOSEL 5.4 2/5] ASoC: rt5645: Make LattePanda board DMI match more precise

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 551539a8606e28cb2a130f8ef3e9834235b456c4 ]

The DMI strings used for the LattePanda board DMI quirks are very generic.

Using the dmidecode database from https://linux-hardware.org/ shows
that the chosen DMI strings also match the following 2 laptops
which also have a rt5645 codec:

Insignia NS-P11W7100 https://linux-hardware.org/?computer=E092FFF8BA04
Insignia NS-P10W8100 https://linux-hardware.org/?computer=AFB6C0BF7934

All 4 hw revisions of the LattePanda board have "S70CR" in their BIOS
version DMI strings:

DF-BI-7-S70CR100-*
DF-BI-7-S70CR110-*
DF-BI-7-S70CR200-*
LP-BS-7-S70CR700-*

See e.g. https://linux-hardware.org/?computer=D98250A817C0

Add a partial (non exact) DMI match on this string to make the LattePanda
board DMI match more precise to avoid false-positive matches.

[PATCH AUTOSEL 5.4 3/5] x86/xen: Add some null pointer checking to smp.c

[Sasha Levin]

From: Kunwu Chan <chentao@kylinos.cn>

[ Upstream commit 3693bb4465e6e32a204a5b86d3ec7e6b9f7e67c2 ]

kasprintf() returns a pointer to dynamically allocated memory
which can be NULL upon failure. Ensure the allocation was successful
by checking the pointer validity.

[PATCH AUTOSEL 5.4 4/5] MIPS: Clear Cause.BD in instruction_pointer_set

[Sasha Levin]

From: Jiaxun Yang <jiaxun.yang@flygoat.com>

[ Upstream commit 9d6e21ddf20293b3880ae55b9d14de91c5891c59 ]

Clear Cause.BD after we use instruction_pointer_set to override
EPC.

This can prevent exception_epc check against instruction code at
new return address.
It won't be considered as "in delay slot" after epc being overridden
anyway.
