Below is the order and stable kernel revisions:
6403298c58d4 ("bus: mhi: core: Fix check for syserr at power_up") #5.10
47705c084659 ("bus: mhi: core: Clear configuration from channel context during reset") #5.10
ec32332df764 ("bus: mhi: core: Sanity check values from remote device before use") #5.10
8de5ad994143 ("bus: mhi: core: Add missing checks for MMIO register entries") #5.11
0fccbf0a3b69 ("bus: mhi: pci_generic: Remove WQ_MEM_RECLAIM flag from state workqueue") #5.11
4547a749be99 ("bus: mhi: core: Fix MHI runtime_pm behavior") #5.12
0ecc1c70dcd3 ("bus: mhi: core: Fix invalid error returning in mhi_queue") #5.12
