MIPS: pass non-NULL dev_id on shared request_irq()

2020-03-16T15:04:49+00:00

Recently all usages of setup_irq() was replaced by request_irq(). request_irq() does a few sanity checks that were not done in setup_irq(), if they fail irq registration will fail. One of the check is to ensure that non-NULL dev_id is passed in the case of shared irq. This caused malta on qemu to hang. Fix it by passing handler as dev_id to all request_irq()'s that are shared. For sni, instead of passing non-NULL dev_id, remove shared irq flags.

MIPS: Replace setup_irq() by request_irq()

2020-03-05T15:47:35+00:00

request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq(). remove_irq() has been replaced by free_irq() as well. There were build error's during previous version, couple of which was reported by kbuild test robot of which one was reported by Thomas Bogendoerfer as well. There were a few more issues including build errors, those also have been fixed.

ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig Acked-by: Arnd Bergmann
