CVE-2025-22095 Information

Description

In the Linux kernel the following vulnerability has been resolved:

PCI: brcmstb: Fix error path after a call to regulator_bulk_get()

If the regulator_bulk_get() returns an error and no regulators are created we need to set their number to zero.

If we don’t do this and the PCIe link up fails a call to the regulator_bulk_free() will result in a kernel panic.

While at it print the error value as we cannot return an error upwards as the kernel will WARN() on an error from add_bus().
