CVE-2026-74303

Bluetooth: hci_qca: fix NULL pointer dereference in qca_dmp_hdr() for non-serdev device

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: hci_qca: fix NULL pointer dereference in qca_dmp_hdr() for non-serdev device

hu->serdev is NULL for hci_uart attached via non-serdev paths, but
qca_dmp_hdr() unconditionally dereferences hu->serdev->dev.driver->name,
causing a NULL pointer dereference.

Fix by guarding the dereference with a NULL check and falling back to
"hci_ldisc_qca" for the non-serdev case.
