xe_guc_print_info is void-returning, but the function pointer it is assigned to expects an int-returning function, leading to the following CFI error: [ 206.873690] CFI failure at guc_debugfs_show+0xa1/0xf0 [xe] (target: xe_guc_print_info+0x0/0x370 [xe]; expected type: 0xbe3bc66a) Fix this by updating xe_guc_print_info to return an integer.
