[PATCH 0/3] media: qcom: iris: improve error diagnostics

[Dipayaan Roy <dipayaan.roy@oss.qualcomm.com>]

The Iris driver can return probe errors or enter error states without
logging enough context to identify the failed operation or firmware
response. This makes failures difficult to diagnose from kernel logs.

Improve probe error reporting, include available return codes and status
values in existing messages, and add focused diagnostics for system and
session failures. Report recovery failures and provide debug-level
messages for successful recovery and less actionable events.
