Subject: [PATCH] x86/sev: clean up initialization of variables info and v
Date: Fri, 26 Nov 2021 22:36:58 +0000 [thread overview]
Message-ID: <20211126223658.1150141-1-colin.i.king@gmail.com> (raw)
Currently variable info is being assigned twice, the second assignment
is redundant. Clean up the code by making the assignments at declaration
time and remove the latter two assignments.
