Subject: [patch V5 26/39] x86/microcode: Clean up mc_cpu_down_prep()
From: Thomas Gleixner <tglx@...utronix.de>
This function has nothing to do with suspend. It's a hotplug
callback. Remove the bogus comment.
Drop the pointless debug printk. The hotplug core provides tracepoints
which track the invocation of those callbacks.
