+Subject: i2c: i801: fix potential race in i801_block_transaction_byte_by_byte
+
+From: Heiner Kallweit <hkallweit1@gmail.com>
+
+commit f78ca48a8ba9cdec96e8839351e49eec3233b177 upstream.
+
+Currently we set SMBHSTCNT_LAST_BYTE only after the host has started
+receiving the last byte. If we get e.g. preempted before setting
+SMBHSTCNT_LAST_BYTE, the host may be finished with receiving the byte
+before SMBHSTCNT_LAST_BYTE is set.
+Therefore change the code to set SMBHSTCNT_LAST_BYTE before writing
+SMBHSTSTS_BYTE_DONE for the byte before the last byte. Now the code
+is also consistent with what we do in i801_isr_byte_done().

+
+From: Sean Young <sean@mess.org>
+
+commit c8a489f820179fb12251e262b50303c29de991ac upstream.
+
+When transmitting, infrared drivers expect an odd number of samples; iow
+without a trailing space. No problems have been observed so far, so
+this is just belt and braces.

+Subject: media: venus: hfi: add checks to handle capabilities from firmware
+
+From: Vikash Garodia <quic_vgarodia@quicinc.com>
+
+commit 8d0b89398b7ebc52103e055bf36b60b045f5258f upstream.
+
+The hfi parser, parses the capabilities received from venus firmware and
+copies them to core capabilities. Consider below api, for example,
+fill_caps - In this api, caps in core structure gets updated with the
+number of capabilities received in firmware data payload. If the same api
+is called multiple times, there is a possibility of copying beyond the max
+allocated size in core caps.
+Similar possibilities in fill_raw_fmts and fill_profile_level functions.

+Subject: media: venus: hfi_parser: Add check to keep the number of codecs within range
+
+From: Vikash Garodia <quic_vgarodia@quicinc.com>
+
+commit 0768a9dd809ef52440b5df7dce5a1c1c7e97abbd upstream.
+
+Supported codec bitmask is populated from the payload from venus firmware.
+There is a possible case when all the bits in the codec bitmask is set. In
+such case, core cap for decoder is filled and MAX_CODEC_NUM is utilized.
+Now while filling the caps for encoder, it can lead to access the caps
+array beyong 32 index. Hence leading to OOB write.
+The fix counts the supported encoder and decoder. If the count is more than
+max, then it skips accessing the caps.

+Subject: net: dsa: lan9303: consequently nested-lock physical MDIO
+
+From: Alexander Sverdlin <alexander.sverdlin@siemens.com>
+
+commit 5a22fbcc10f3f7d94c5d88afbbffa240a3677057 upstream.
+
+When LAN9303 is MDIO-connected two callchains exist into
+mdio->bus->write():
+
+1. switch ports 1&2 ("physical" PHYs):
+
+virtual (switch-internal) MDIO bus (lan9303_switch_ops->phy_{read|write})->
+ lan9303_mdio_phy_{read|write} -> mdiobus_{read|write}_nested
+
+2. LAN9303 virtual PHY:
+
+virtual MDIO bus (lan9303_phy_{read|write}) ->
+ lan9303_virt_phy_reg_{read|write} -> regmap -> lan9303_mdio_{read|write}
+
+If the latter functions just take
+mutex_lock(&sw_dev->device->bus->mdio_lock) it triggers a LOCKDEP
+false-positive splat. It's false-positive because the first
+mdio_lock in the second callchain above belongs to virtual MDIO bus, the
+second mdio_lock belongs to physical MDIO bus.
+
+Consequent annotation in lan9303_mdio_{read|write} as nested lock
+(similar to lan9303_mdio_phy_{read|write}, it's the same physical MDIO bus)
+prevents the following splat:
+

+Subject: Revert ncsi: Propagate carrier gain/loss events to the NCSI controller
+
+From: Johnathan Mantey <johnathanx.mantey@intel.com>
+
+commit 9e2e7efbbbff69d8340abb56d375dd79d1f5770f upstream.
+
+This reverts commit 3780bb29311eccb7a1c9641032a112eed237f7e3.
+
+The cited commit introduced unwanted behavior.
+
+The intent for the commit was to be able to detect carrier loss/gain
+for just the NIC connected to the BMC. The unwanted effect is a
+carrier loss for auxiliary paths also causes the BMC to lose
+carrier. The BMC never regains carrier despite the secondary NIC
+regaining a link.
+
+This change, when merged, needs to be backported to stable kernels.
+5.4-stable, 5.10-stable, 5.15-stable, 6.1-stable, 6.5-stable
+
+Fixes: 3780bb29311e ("ncsi: Propagate carrier gain/loss events to the NCSI controller")
