Enabling in-band sleep when there is no patch/nvm-config found and
bluetooth is running with the original fw/config.
Fixes: ba8f35979002 ("Bluetooth: hci_qca: Avoid setup failure on missing rampatch")
Fixes: 7dc5fe0814c3 ("Bluetooth: hci_qca: Avoid missing rampatch failure with userspace fw loader")

Hi Claire,
This change will not work as we need fw files to be loaded tofor IBS to
active.
may i know on which chipset you have this issue of IBS active even with
out fw download.

Hi Balakrishna,
Sorry for the late reply. I was on vacation for the past few days.
The chipset we use is QCA6174A-3 and rjliao has already confirmed that
IBS won't work without RAM fw downloaded.
Please ignore this change.
Thanks,
Claire
