We need to apply 2685c77b80a8 ("thermal/drivers/int340x: Fix RFIM mailbox write commands") to the 5.15-stable tree but it does not apply. This patch fix the write operation for mailbox command for RFIM (cmd = 0x08) which is ignored. This results in failing to store RFI restriction.
To apply this fix, we need to backport below set of three patches on 5.15-stable tree because this fix depended on these three patches. Without these three dependent patches, we cannot directly apply fix (fourth) patch.
Backport three patches: [1] c4fcf1ada4ae ("thermal/drivers/int340x: Improve the tcc offset saving for suspend/resume") [2] aeb58c860dc5 ("thermal/drivers/int340x: processor_thermal: Suppot 64 bit RFIM responses") [3] 994a04a20b03 ("thermal: int340x: Limit Kconfig to 64-bit")
Fix RFIM patch: [4] 2685c77b80a8 ("thermal/drivers/int340x: Fix RFIM mailbox write commands")
--- Changes in V2 from V1: - Added upstream commit id from Linus's tree for all four patches. ---
