Subject: [PATCH] dmaengine: ti: k3-udma-glue: Fix of_k3_udma_glue_parse_chn_by_id()
Date: Sat, 18 May 2024 15:35:56 +0530
Message-ID: <20240518100556.2551788-1-s-vadapalli@ti.com>

The of_k3_udma_glue_parse_chn_by_id() helper function erroneously
invokes "of_node_put()" on the "udmax_np" device-node passed to it,
without having incremented its reference at any point. Fix it.

Hello,

This patch is based on commit
