From 9712c092cf06be9934e92ee2919e901afb981b6a Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Mon, 18 May 2020 12:02:39 -0600 Subject: coresight: Avoid casting void pointers We don't need to cast void pointers, such as the amba_id data. Assign to a local variable to make the code prettier and also return NULL instead of 0 to make sparse happy.
