Subject: [PATCH 5.4 154/232] powerpc/pseries: Drop pointless static qualifier in vpa_debugfs_init()

From: YueHaibing <yuehaibing@...wei.com>

commit 11dd34f3eae5a468013bb161a1dcf1fecd2ca321 upstream.

There is no need to have the 'struct dentry *vpa_dir' variable static
since new value always be assigned before use it.

Fixes: c6c26fb55e8e ("powerpc/pseries: Export raw per-CPU VPA data via debugfs")
