media: sta2x11: fix irq handler cast
[ Upstream commit 3de49ae81c3a0f83a554ecbce4c08e019f30168e ]
clang-16 warns about casting incompatible function pointers:
drivers/media/pci/sta2x11/sta2x11_vip.c:1057:6: error: 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 [-Werror,-Wcast-function-type-strict]
Change the prototype of the irq handler to the regular version with a
local variable to adjust the argument type.
