From 200543c1b94da9249b35ea1b8726cd0cdee128d5 Mon Sep 17 00:00:00 2001 From: Bryan O'Donoghue Date: Mon, 6 Nov 2017 01:32:21 +0000 Subject: staging: greybus: operation: add private data with get/set accessors Asynchronous operation completion handler's lives are made easier if there is a generic pointer that can store private data associated with the operation. This patch adds a pointer field to struct gb_operation and get/set methods to access that pointer.
