Since commitd59f6617ee("genirq: Allow fwnode to carry name information only") the irqdomain core sets the names of irq domains. When the name is allocated the new IRQ_DOMAIN_NAME_ALLOCATED flag is set. Replacing the allocated name with a constant one is not a good idea, since calling the new irq_domain_update_bus_token() API, added to the MIPS GIC driver by commit96f0d93a48("irqchip/MSI: Use irq_domain_update_bus_token instead of an open coded access") will attempt to kfree the pointer, and result in a kernel OOPS. Fix this by removing the names, now that they are set by the irqdomain core. This effectively reverts commit21c57fd135("irqchip/mips-gic: Populate irq_domain names").

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
