Subject: [PATCH 03/12] x86/microcode/intel: Simplify generic_load_microcode()
Date: Tue, 25 Oct 2016 11:55:13 +0200	[thread overview]
Message-ID: <20161025095522.11964-4-bp@alien8.de> (raw)
In-Reply-To: <20161025095522.11964-1-bp@alien8.de>

From: Borislav Petkov <bp@suse.de>

Make it return the ucode_state directly instead of assigning to a state
variable and jumping to an out: label.

No functionality change.
