Subject: [PATCH 472/534] rtw89: don't flush hci queues and send h2c if power
|
|
is off
|
|
|
|
When disconnecting, it warns somethings after power is off, and we can't
|
|
do HCI IO. So, add this patch to avoid below messages:
|
|
|
|
rtw89_8852ce 0000:03:00.0: timed out to flush pci txch: 11
|
|
rtw89_8852ce 0000:03:00.0: failed to pre-release fwcmd
