Subject[PATCH] firmware: qcom_scm: Prefer initialisation during the descriptor declaration
Date
qcom_scm_iommu_secure_ptbl_init() initialises the args twice, once while
declaring the struct, and then again by assignment. Remove the duplicate
assignment.

Similarly, move arginfo initialisation to the declaration in
__qcom_scm_is_call_available for consistency with other .arginfo
initialisation in the file.

Fixes: 9a434cee773a ("firmware: qcom_scm: Dynamically support SMCCC and legacy conventions")
