Subject: [PATCH v6 1/8] PCI/VGA: Use unsigned type for the io_state variable

From: Sui Jingfeng <suijingfeng@...ngson.cn>

The io_state variable in the vga_arb_write() function is declared with
unsigned int type, while the vga_str_to_iostate() function takes int *
type. To keep them consistent, replace the third argument of
vga_str_to_iostate() function with the unsigned int * type.
