From c92ab8aaf42e84f33d690ea9cb292483dd9c2761 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Tue, 23 Jan 2024 12:46:30 -0600 Subject: [PATCH] remoteproc: qcom_wcnss: Use devm_rproc_alloc() helper Use the device lifecycle managed allocation function. This helps prevent mistakes like freeing out of order in cleanup functions and forgetting to free on error paths.
