Subject[PATCH 4.19 34/51] net: sxgbe: fix return value of __setup handler
Date
From: Randy Dunlap <rdunlap@infradead.org>

commit 50e06ddceeea263f57fe92baa677c638ecd65bb6 upstream.

__setup() handlers should return 1 on success, i.e., the parameter
has been handled. A return of 0 causes the "option=value" string to be
added to init's environment strings, polluting it.

Fixes: acc18c147b22 ("net: sxgbe: add EEE(Energy Efficient Ethernet) for Samsung sxgbe")
Fixes: 1edb9ca69e8a ("net: sxgbe: add basic framework for Samsung 10Gb ethernet driver")
