Subject: [PATCH 3/5] x86/microcode: Kill refresh_fw
Date: Wed, 19 Oct 2022 19:54:24 +0200 [thread overview]
Message-ID: <20221019175426.31025-3-bp@alien8.de> (raw)
In-Reply-To: <20221019175426.31025-1-bp@alien8.de>
From: Borislav Petkov <bp@suse.de>
request_microcode_fw() can always request firmware now so drop this
superfluous argument.
