Subject: [PATCH 4/6] KVM: SEV: Drop a redundant setting of sev->asid during
initialization
Git-commit: ea410ef4dad6282420bde00e1ffca874344f0e95
Patch-mainline: v5.16-rc2
References: bsc#1194526
Remove a fully redundant write to sev->asid during SEV/SEV-ES guest
initialization. The ASID is set a few lines earlier prior to the call to
sev_platform_init(), which doesn't take "sev" as a param, i.e. can't
muck with the ASID barring some truly magical behind-the-scenes code.
No functional change intended.
