From 900470ce39996336a1d06da2015506106bb8ba42 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Thu, 28 Nov 2019 15:55:42 +0100 Subject: soc: fsl: qe: make cpm_muram_free() ignore a negative offset This allows one to simplify callers since they can store a negative value as a sentinel to indicate "this was never allocated" (or store the -ENOMEM from an allocation failure) and then call cpm_muram_free() unconditionally.
