Subject: lan743x: fix use of uninitialized variable
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=edbc21113bde13ca3d06eec24b621b1f628583dd;p=linux.git

lan743x: fix use of uninitialized variable

When no devicetree is present, the driver will use an
uninitialized variable.

Fix by initializing this variable.
