From d3febddde9c7a959dbb189a700e937db50fad4d6 Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Tue, 25 Aug 2015 17:05:46 +0800 Subject: [PATCH] kvm: use kmalloc() instead of kzalloc() during iodev register/unregister All fields of kvm_io_range were initialized or copied explicitly afterwards. So switch to use kmalloc(). Cc: Gleb Natapov Cc: Paolo Bonzini Cc: Michael S.
