[PATCH 3.16 285/306] ser_gigaset: return -ENOMEM on error instead of success

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.16.40-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit 93a97c50cbf1c007caf12db5cc23e0d5b9c8473c upstream.

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