Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2084225

[ Upstream commit b3181f433206a1432bc7093d1896fe36026f7fff ]

The if condition !A || A && B can be simplified to !A || B.

Fixes the following Coccinelle/coccicheck warning reported by
excluded_middle.cocci:

	WARNING !A || A && B is equivalent to !A || B

Compile-tested only.
