PS4, Line 351: printk(BIOS_DEBUG, "GPE0 STD STS: ");
             : 
             : 	sts_arr = soc_std_gpe_sts_array(&array_size);
             : 	if (array_size == 0)
             : 		return 0;
             : 	print_num_status_bits(array_size, gpe_sts, sts_arr);
             : 	printk(BIOS_DEBUG, "\n");
I'd still print the newline so as not to mess up the formatting:

```suggestion
    printk(BIOS_DEBUG, "GPE0 STD STS: ");

sts_arr = soc_std_gpe_sts_array(&array_size);
    if (array_size > 0)
    	print_num_status_bits(array_size, gpe_sts, sts_arr);
    printk(BIOS_DEBUG, "\n");
```
