From b5c16ea57b030b8e9428ec726e26219dfe05c3d9 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Fri, 26 Sep 2025 16:35:10 +0200 Subject: [PATCH] soc: qcom: ocmem: fix device leak on lookup Make sure to drop the reference taken to the ocmem platform device when looking up its driver data. Note that holding a reference to a device does not prevent its driver data from going away so there is no point in keeping the reference. Also note that commit 0ff027027e05 ("soc: qcom: ocmem: Fix missing put_device() call in of_get_ocmem") fixed the leak in a lookup error path, but the reference is still leaking on success.
