Subject: [PATCH 1/3] media: pci: sta2x11: Fix Wcast-function-type-strict
 warnings

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]
