Subject: [PATCH AUTOSEL 5.4 3/6] net/iucv: fix the allocation size of iucv_path_table array
From: Alexander Gordeev <agordeev@...ux.ibm.com>
[ Upstream commit b4ea9b6a18ebf7f9f3a7a60f82e925186978cfcf ]
iucv_path_table is a dynamically allocated array of pointers to
struct iucv_path items. Yet, its size is calculated as if it was
an array of struct iucv_path items.
