From edef6576853e51faa11bb286884c362ff7fc83a0 Mon Sep 17 00:00:00 2001 From: Pauli Virtanen Date: Tue, 3 Feb 2026 21:57:21 +0200 Subject: [PATCH] Bluetooth: hci_core: Rate limit the logging of invalid ISO handle Some controller firmwares (eg for MT7925) continuously send invalid ISO packet, which result to "ISO unknown handle" error spam in logs. It's not important to show all of them to the user. Rate limit these ISO error messages, similarly as we do for SCO.
