Thomas Gleixner 03992c88d7 irqdomain/treewide: Keep firmware node unconditionally allocated ... [ Upstream commit e3beca48a4 ] Quite some non OF/ACPI users of irqdomains allocate firmware nodes of type IRQCHIP_FWNODE_NAMED or IRQCHIP_FWNODE_NAMED_ID and free them right after creating the irqdomain. The only purpose of these FW nodes is to convey name information. When this was introduced the core code did not store the pointer to the node in the irqdomain. A recent change stored the firmware node pointer in irqdomain for other reasons and missed to notice that the usage sites which do the alloc_fwnode/create_domain/free_fwnode sequence are broken by this. Storing a dangling pointer is dangerous itself, but in case that the domain is destroyed later on this leads to a double free. Remove the freeing of the firmware node after creating the irqdomain from all affected call sites to cure this. Fixes: 711419e504 ("irqdomain: Add the missing assignment of domain->fwnode for named fwnode") Reported-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Marc Zyngier <maz@kernel.org> Cc: stable@vger.kernel.org Link: https://lkml.kernel.org/r/873661qakd.fsf@nanos.tec.linutronix.de Signed-off-by: Sasha Levin <sashal@kernel.org>		2020-07-29 07:42:52 +02:00
