## Overview

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().

## Affected

- `linux_kernel >= 6.0, < 6.1.134`
- `linux_kernel >= 6.2, < 6.6.87`
- `linux_kernel >= 6.7, < 6.12.23`
- `linux_kernel >= 6.13, < 6.13.11`
- `linux_kernel >= 6.14, < 6.14.2`

## Remediation
