From 52033fdebc92021490729465e27ffb47cd42b0e0 Mon Sep 17 00:00:00 2001 From: Vaibhav Agarwal Date: Fri, 27 May 2016 10:49:24 +0530 Subject: [PATCH] greybus: es2: Release reserved cports CDSI0 and CDSI1 Unique ids were reserved for CDSI0 and CDSI1 during _probe, however missed to release those ids during disconnect. This causes a memory leak of 128 bytes for each iteration of unipro_reset. Fix this.
