[GIT PULL] samsung: drivers firmware for v7.1, replacement

[Krzysztof Kozlowski]

Hi Arnd and SoC folks,

This is a replacement/rework pull of previous tags/samsung-drivers-fixes-7.1.
I also dropped that tag from my repo.

Changes against previous pull:
1. Drop commit: firmware: samsung: acpm: Fix dummy stubs to return ERR_PTR
2. Drop commit: firmware: samsung: acpm: Add memory barrier before advancing RX pointer

This caused rewritten history, but all of the commits were already in next
since May 14.


Best regards,
Krzysztof

  firmware: samsung: acpm: Fix infinite loop on sequence number exhaustion (2026-05-29 14:11:23 +0200)

----------------------------------------------------------------
Samsung SoC driver fixes for v7.1

Fix several concurrency issues present in Samsung ACPM firmware drivers,
used currently only on Google GS101.  Tudor with help of Sashiko
identified several missing barriers and incomplete synchronization,
leading to possible transfer data corruption or use after free.  Few
other issues related to probe, including missing mailbox cleanup, were
also fixed.
