[PATCH ath-next] wifi: ath12k: wmi: Complete regulatory update for dropped events

From: Konrad Dybcio

Date: Tue Aug 18 2026 - 10:57:22 EST


From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>

If ath12k_reg_validate_reg_info() returns STATUS_FALLBACK/DROP (which
are not fatal), the code then jumps to mem_free with pdev_idx still set
to 255, making the following completion never take place.

That then results in repeating "Timeout while waiting for regulatory
update" messages, as observed e.g. on a Glymur-based ASUS Zenbook A16.

Fix that by updating the pdev_idx right after the actually-fatal case
of not being able to extract the reg info data is ruled out.

Fixes: 906619a00967 ("wifi: ath12k: handle regulatory hints during mac registration")
