[PATCH phosphor-host-ipmid 1/3] Remove unused code
OpenBMC Patches
openbmc-patches at stwcx.xyz
Tue Mar 15 14:20:30 AEDT 2016
From: Cyril Bur <cyril.bur at au1.ibm.com>
Several calls to sd_bus methods pass pointers to an error variable and a reply
variable which are not ever used. These must later be unrefed to avoid memory
leaks.
This change removes this code to improve maintainability and avoid future
leaks.
