From 7ddae24f97f9fc8f151aae75f0371ced06a8cd99 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 20 May 2018 19:04:24 -0400 Subject: mv88e6xxx: Fix uninitialized variable warning. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In mv88e6xxx_probe(), ("np" or "pdata") might be an invariant but GCC can't see that, therefore: drivers/net/dsa/mv88e6xxx/chip.c: In function ‘mv88e6xxx_probe’: drivers/net/dsa/mv88e6xxx/chip.c:4420:13: warning: ‘compat_info’ may be used uninitialized in this function [-Wmaybe-uninitialized] chip->info = compat_info; Actually, it should have warned on the "if (!compat_info)" test, but whatever. Explicitly initialize to NULL in the variable declaration to deal with this. Fixes: 877b7cb0b6f2 ("net: dsa: mv88e6xxx: Add minimal platform_data support") Signed-off-by: David S.
