[Qemu-devel] [PATCH for-3.2 v5 16/19] RFC: arm: replace instance_post_in


From: Marc-André Lureau
Subject: [Qemu-devel] [PATCH for-3.2 v5 16/19] RFC: arm: replace instance_post_init()
Date: Tue, 4 Dec 2018 18:20:20 +0400

Replace arm_cpu_post_init() instance callback by calling it from leaf
classes, to avoid potential ordering issue with other post_init callbacks.

Note: this patch is no longer needed in this series, since the
compat-props interface approach was abandoned.
