Subject: [PATCH] of: Make of_match_node() an inline stub for CONFIG_OF=n
Date: Thu,  6 Apr 2017 12:32:24 -0700	[thread overview]
Message-ID: <20170406193224.10046-1-f.fainelli@gmail.com> (raw)

Make of_match_node() an inline function when CONFIG_OF=n which allows the
compiler to eliminate warnings about unused variables.

Suggested-by: Andrew Lunn <andrew-g2DYL2Zd6BY@public.gmane.org>
