Subject: [PATCH 07/13] x86/microcode: Move late-load warning to earlier where kernel taint happens
Date: Fri, 14 Oct 2022 13:09:07 -0700 [thread overview]
Message-ID: <20221014200913.14644-8-ashok.raj@intel.com> (raw)
In-Reply-To: <20221014200913.14644-1-ashok.raj@intel.com>
Move where the late loading warning is being issued to earlier in the call.
This would put the warn and taint in the same function.
Just a tidy thing, no functional changes.
