[PATCH 1/2] powerpc/83xx: Fix style problems in usb.c and remove unneccessary includes from mpc83xx.h

From: Christophe Leroy
Date: Wed Aug 16 2023 - 11:23:18 EST


Replace printk(KERN_WARN with pr_warn(

Remove a couple of blank lines

Re-align multi-line code.

Replace asm/io.h by linux/io.h

mpc83xx.h doesn't need linux/device.h or asm/pci-bridge.h
