From b442377c0ea2044a8f50ffa3fe59448f9ed922c9 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 22 Dec 2025 21:33:25 +0100 Subject: [PATCH] dmaengine: sh: Discard pm_runtime_put() return value Clobbering an error value to be returned from shdma_tx_submit() with a pm_runtime_put() return value is not particularly useful, especially if the latter is 0, so stop doing that. This will facilitate a planned change of the pm_runtime_put() return type to void in the future. Signed-off-by: Rafael J.
