Subject: [PATCH] ASoC: Intel: avs: Fix kcalloc() sizes
Date: Sat, 26 Apr 2025 16:13:41 +0200	[thread overview]
Message-ID: <20250426141342.94134-2-thorsten.blum@linux.dev> (raw)

rlist, clist, and slist are allocated using sizeof(pointer) instead of
sizeof(*pointer). Fix the allocations by using sizeof(*pointer) and
avoid overallocating memory on 64-bit systems.

Fixes: f2f847461fb7 ("ASoC: Intel: avs: Constrain path based on BE capabilities")
