+Subject: drm/i915/dp: Initialize the source OUI write timestamp always
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit

+
+commit 5861258c4e6a829a10200b41ba3fb4d7d1a4054f upstream.
+
+If the source OUI DPCD register value matches the expected Intel OUI
+value, the write timestamp doesn't get updated leaving it at the 0
+initial value if the OUI wasn't written before. This can lead to an
+incorrect wait duration in intel_dp_wait_source_oui(), since jiffies is
+not inited to 0 in general (on a 32 bit system INITIAL_JIFFIES is set to
+5 minutes ahead of wrap-around). Fix this by intializing the write
+timestamp in the above case as well.

+Subject: Revert "ACPI: Suppress misleading SPCR console message when SPCR table is absent"
+
+From: Punit Agrawal <punit.agrawal@oss.qualcomm.com>
+
+commit eeb8c19896952e18fb538ec76e603884070a6c6a upstream.
+
+This reverts commit bad3fa2fb9206f4dcec6ddef094ec2fbf6e8dcb2.
+
+Commit bad3fa2fb920 ("ACPI: Suppress misleading SPCR console message
+when SPCR table is absent") mistakenly assumes acpi_parse_spcr()
+returning 0 to indicate a failure to parse SPCR. While addressing the
+resultant incorrect logging it was deemed that dropping the message is
+a better approach as it is not particularly useful.
+
+Roll back the commit introducing the bug as a step towards dropping
+the log message.

+Subject: wifi: ath12k: correctly handle mcast packets for clients
+
+From: Sarika Sharma <quic_sarishar@quicinc.com>
+
+commit 4541b0c8c3c1b85564971d497224e57cf8076a02 upstream.
+
+Currently, RX is_mcbc bit is set for packets sent from client as
+destination address (DA) is multicast/broadcast address, but packets
+are actually unicast as receiver address (RA) is not multicast address.
+Hence, packets are not handled properly due to this is_mcbc bit.
+
+Therefore, reset the is_mcbc bit if interface type is AP.
