Subject: [PATCH RESEND 0/2] Bluetooth: qca: fix NULL-deref on non-serdev setup

Qualcomm Bluetooth controllers can be registered either from a serdev
driver or from the Bluetooth line discipline. In the latter case, the
HCI UART serdev pointer is NULL, something which the driver needs to
handle without crashing.

This series fixes one such issue at setup() time which incidentally
masked a similar crash at suspend. Fix this in two separate patches so
that the latter issue is addressed in pre-6.2 stable kernels.
