Subject: [PATCH] irqchip: riscv-imsic: Fixup riscv_ipi_set_virq_range() conflict

From: Palmer Dabbelt <[email protected]>

There was a semantic conflict between 21a8f8a0eb35 ("irqchip: Add RISC-V
incoming MSI controller early driver") and dc892fb44322 ("riscv: Use
IPIs for remote cache/TLB flushes by default") due to an API change.
This manifests as a build failure post-merge.

Sorry I wasn't clear about this one, but looks like it got dropped as
part of the merge. I'm happy to pick this up via the RISC-V tree if
folks want, but I'll keep it stashed off to the side for now as it's
just touching irqchip. I'm planning on sending some more stuff on
Friday morning, so just LMK.
