[PATCH][next] KVM: x86: simplify zero'ing of entry->ebx
From: Colin King
Date: Thu Apr 22 2021 - 10:12:06 EST
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently entry->ebx is being zero'd by masking itself with zero.
Simplify this by just assigning zero, cleans up static analysis
warning.
Addresses-Coverity: ("Bitwise-and with zero")
