Subject: [patch] ser_gigaset: return -ENOMEM on error instead of success
Date: Wed, 7 Dec 2016 14:22:03 +0300	[thread overview]
Message-ID: <20161207112203.GC5507@elgon.mountain> (raw)

If we can't allocate the resources in gigaset_initdriver() then we
should return -ENOMEM instead of zero.

Fixes: 2869b23e4b95 ("[PATCH] drivers/isdn/gigaset: new M101 driver (v2)")
