From 36a9d79e5e9518dfd9548e3237e7a49464c16922 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Thu, 5 Aug 2021 00:07:06 -0500 Subject: [PATCH] ASoC: simple-card-utils: Avoid over-allocating DLCs The allocation of the DAI link components (DLCs) passed the wrong pointer to sizeof. Since simple_dai_props is much larger than snd_soc_dai_link_component, there was no out of bounds access, only wasted memory.
