Subject: [GIT PULL] AMDTEE driver fixes for v5.10

Hello arm-soc maintainers,

Please pull these AMDTEE driver fixes which are needed when opening multiple
contexts or file descriptors.

Note that this isn't a usual Arm driver update. This targets x86/AMD instead,
but is still part of the TEE subsystem.

Thanks,
Jens

AMD-TEE driver bug fixes

AMD-TEE driver keeps track of shared memory buffers and their
corresponding buffer id's in a global linked list. These buffers are
used to share data between x86 and AMD Secure Processor. This pull
request fixes issues related to maintaining mapped buffers in a shared
linked list.
