From: Peter Maydell Date: Mon, 17 Jul 2017 12:36:06 +0000 (+0100) Subject: qdev-properties.h: Explicitly set the default value for arraylen properties X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d9a7b125d6b8048a503d10117ee8b7cbc44cc889;p=qemu.git qdev-properties.h: Explicitly set the default value for arraylen properties In DEFINE_PROP_ARRAY, because we use a PropertyInfo (qdev_prop_arraylen) which has a .set_default_value member we will set the field to a default value. That default value will be zero, by the C rule that struct initialization sets unmentioned members to zero if at least one member is initialized. However it's clearer to state it explicitly.
