[ 49/82] target: Dont return success from module_init() if setup fails
From: Ben Hutchings
Date: Wed Nov 14 2012 - 00:59:25 EST
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Roland Dreier <roland@xxxxxxxxxxxxxxx>
commit 0d0f9dfb31e0a6c92063e235417b42df185b3275 upstream.
If the call to core_dev_release_virtual_lun0() fails, then nothing
sets ret to anything other than 0, so even though everything is
torn down and freed, target_core_init_configfs() will seem to succeed
and the module will be loaded. Fix this by passing the return value
on up the chain.
