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().

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: PCI: brcmstb: Corrección de la ruta de error tras una llamada a regulator_bulk_get(). Si regulator_bulk_get() devuelve un error y no se crean reguladores, debemos establecer su número en cero. Si no lo hacemos y falla la conexión PCIe, una llamada a regulator_bulk_free() provocará un pánico del kernel. Mientras tanto, imprima el valor del error, ya que no podemos devolver un error hacia arriba, ya que el kernel emitirá una advertencia WARN() en caso de un error de add_bus().
