Building with LLVM=1 throws the following warning:
drivers/media/pci/sta2x11/sta2x11_vip.c:1057:6: warning: cast from 'irqreturn_t (*)(int, struct sta2x11_vip *)' (aka 'enum irqreturn (*)(int, struct sta2x11_vip *)') to 'irq_handler_t' (aka 'enum irqreturn (*)(int, void *)') converts to incompatible function type [-Wcast-function-type-strict]

Arnd's patch for this has already been merged:

https://lore.kernel.org/linux-media/20240213095451.454142-1-arnd@kernel.org/

So I'm marking your patch as 'Obsolete' in patchwork.

Regards,
