[PATCH 0/2] qcom_tzmem: Enhance Error Handling for shmbridge

[Kuldeep Singh <quic_kuldsing@xxxxxxxxxxx>]

This patchset addresses the tzmem driver probe failure caused by
incorrect error handling. The qcom_scm_shm_bridge_enable() SCM call
captures SCM success/failure in a0 and E_NOT_SUPPORTED in a1.

Previously, qcom_scm returned values based solely on a0, without
capturing not_supported scenario. This patchset corrects that behavior.

Along with this, add sanity checks on input parameters passed to exposed
APIs as it is missing currently.
