Subject: [PATCH] ASoC: tegra: ADX: convert map to flexible array
Date: Fri, 14 Aug 2026 13:50:18 -0700 [thread overview]
Message-ID: <20260814205018.39015-1-rosenp@gmail.com> (raw)
Replace the pointer-based map allocation with a flexible array
member and use struct_size() for allocation. This simplifies
the code and avoid an extra allocation.
