[PATCH] Bluetooth: hci_sync: use HCI_CMD_TIMEOUT for PA sync commands
From: Yang Li via B4 Relay
Date: Thu Jan 08 2026 - 01:04:23 EST
From: Yang Li <yang.li@xxxxxxxxxxx>
PA sync HCI commands incorrectly use conn->conn_timeout, which defaults
to 20s and is too long. If the PA Sync Established event is not
received, the command remains pending and causes userspace timeouts.
