Subject: xen/privcmd: fix condition in privcmd_close()
X-Git-Tag: firefly_0821_release~3680^2~332^2~21
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9eff37a8713939f218ab8bf0dc93f1d67af7b8b4;p=firefly-linux-kernel-4.4.55.git

xen/privcmd: fix condition in privcmd_close()

The parenthesis are in the wrong place so the original code is
equivalent to:

	if (!xen_feature(XENFEAT_writable_descriptor_tables)) { ...

Which obviously was not intended.
