This patch allows a user space process to enable/disable the quality
report events dynamically through the set experimental feature mgmt
interface if CONFIG_BT_FEATURE_QUALITY_REPORT is enabled.

Since the quality report feature needs to invoke the callback function
provided by the driver, i.e., hdev->set_quality_report, a valid
controller index is required.

we are not doing a CONFIG_BT_FEATURE_QUALITY_REPORT here then. This is getting out of control. What is the harm of always adding this feature? I don’t see a large size impact.

You really need somewhere here is hdev->set_quality_report is set.
