Subject: [PATCH] dmaengine: mediatek: mtk-uart-apdma: Return -ENOMEM on memory allocation failure
Date: Wed, 1 Jul 2026 23:07:03 +0300 [thread overview]
Message-ID: <20260701200703.117929-1-vz@kernel.org> (raw)
If dynamic memory allocation in driver's probe function execution fails, it
should be reported to the driver's framework with -ENOMEM error code.
Fixes: 9135408c3ace ("dmaengine: mediatek: Add MediaTek UART APDMA support")
