From 69d08dcbbe34347cbc044629cf6f25d062593dfe Mon Sep 17 00:00:00 2001 From: John Allen Date: Thu, 18 Jan 2018 16:27:58 -0600 Subject: [PATCH] ibmvnic: Allocate and request vpd in init_resources In reset events in which our memory allocations need to be reallocated, VPD data is being freed, but never reallocated. This can cause issues if we later attempt to access that memory or reset and attempt to free the memory. This patch moves the allocation of the VPD data to init_resources so that it will be symmetrically freed during release resources.
