From 226f5db4212438cdfe1a94652d74c6c01788a837 Mon Sep 17 00:00:00 2001 From: Mathieu Poirier Date: Mon, 20 Apr 2020 17:16:01 -0600 Subject: [PATCH] remoteproc: Get rid of tedious error path Get rid of tedious error management by moving firmware and operation allocation after calling device_initialize(). That way we take advantage of the automatic call to rproc_type_release() to cleanup after ourselves when put_device() is called.
