When hci_qca returns an error to its pm_ops.suspend routine,
the PM subsystem will terminate the system wide suspend.
It is extremely unlikely that there will ever be a justification
for hci_qca, no matter what its internal malfunction, should
cause system-wide suspend to terminate.
Doing so, could result in the scenario where a laptop lid is closed,
suspend termnates, the user places the running laptop into a breifcase,
not expecting it to be overheating or draining its battery...
This is not a theoretical issue.
The 6.3-rc1 currently fails this way on the Dell XPS-13-9310:
Bluetooth: hci0: SSR or FW download time out
hci_uart_qca serial0-0: PM: dpm_run_callback(): acpi_subsys_suspend+0x0/0x70 returns -110
hci_uart_qca serial0-0: PM: failed to suspend: error -110
PM: suspend of devices aborted after 3218.724 msecs
PM: start suspend of devices aborted after 3246.859 msecs
PM: Some devices failed to suspend, or early wake event detected
PM: resume of devices complete after 84.988 msecs
