Subject: [PATCH] Bluetooth: btmtk: Remove the resetting step before downloading the fw
Date: Sat, 15 Mar 2025 10:27:30 +0800 [thread overview]
Message-ID: <20250315022730.11071-1-hao.qin@mediatek.com> (raw)
Remove the resetting step before downloading the fw, as it may cause
other usb devices to fail to initialise when connected during boot
on kernels 6.11 and newer.
