From 6abf9dd26bb1699c17d601b9a292577d01827c0e Mon Sep 17 00:00:00 2001 From: Zijun Hu Date: Fri, 26 Jan 2024 17:00:24 +0800 Subject: Bluetooth: qca: Fix triggering coredump implementation hci_coredump_qca() uses __hci_cmd_sync() to send a vendor-specific command to trigger firmware coredump, but the command does not have any event as its sync response, so it is not suitable to use __hci_cmd_sync(), fixed by using __hci_cmd_send().
