irqchip/al-fic: make AL_FIC depend on HAS_IOMEM
On s390 systems (aka mainframes), it has classic channel devices for networking and permanent storage that are currently even more common than PCI devices. Hence it could have a fully functional s390 kernel with CONFIG_PCI=n, then the relevant iomem mapping functions [including ioremap(), devm_ioremap(), etc.] are not available. Here let AL_FIC depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset: ------ ld: drivers/irqchip/irq-al-fic.o: in function `al_fic_init_dt': irq-al-fic.c:(.init.text+0x76): undefined reference to `of_iomap' ld: irq-al-fic.c:(.init.text+0x4ce): undefined reference to `iounmap' ------ Link: https://lkml.kernel.org/r/20230707135852.24292-7-bhe@redhat.com Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202306211329.ticOJCSv-lkp@intel.com/ Signed-off-by: Baoquan He <bhe@redhat.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Marc Zyngier <maz@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
