Subject: [PATCH 2/3] media: usb: pvrusb2: Fix Wcast-function-type-strict
warnings
Building with LLVM=1 throws the following warning:
drivers/media/usb/pvrusb2/pvrusb2-context.c:110:6: warning: cast from 'void (*)(struct pvr2_context *)' to 'void (*)(void *)' converts to incompatible function type [-Wcast-function-type-strict]
