Subject: x86/ioperm: Initialize pointer bitmap with NULL rather than 0
X-Git-Tag: v5.9-rc1~195^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=90fc73928fec2f62bbee1476781754c7392a7b61;p=thirdparty%2Fkernel%2Flinux.git

x86/ioperm: Initialize pointer bitmap with NULL rather than 0

The pointer bitmap is being initialized with a plain integer 0,
fix this by initializing it with a NULL instead.

Cleans up sparse warning:
arch/x86/xen/enlighten_pv.c:876:27: warning: Using plain integer
as NULL pointer
