[Patch v3 1/3] soc: qcom: mdt_loader: Remove unused parameter

[Patch v3 1/3] soc: qcom: mdt_loader: Remove unused parameter

[Mukesh Ojha]

commit f4e526ff7e38e ("soc: qcom: mdt_loader: Extract PAS
 operations") move pas specific code from __qcom_mdt_load()
to a separate function qcom_mdt_pas_init() after which the
pas_init variable became unused in __qcom_mdt_load().

Remove pas_init argument from __qcom_mdt_load().

[Patch v3 2/3] soc: qcom: mdt_loader: Remove pas id parameter

[Mukesh Ojha]

pas id is not used in qcom_mdt_load_no_init() and it should not
be used as it is non-PAS specific function and has no relation
to PAS specific mechanism.

[Patch v3 3/3] soc: qcom: mdt_loader: Remove unused parameter

[Mukesh Ojha]

fw_name in qcom_mdt_bins_are_split() seems unused now, it may have
used in the past for logging it but due to code refactor this parameter
is unused now.
