Subject: [PATCH v2 1/5] dmaengine: ti: omap-dma: fix missing return in probe error path
Date: Sun, 31 May 2026 17:35:49 -0700	[thread overview]
Message-ID: <20260601003553.72573-2-rosenp@gmail.com> (raw)
In-Reply-To: <20260601003553.72573-1-rosenp@gmail.com>

If of_dma_controller_register() fails, the error path omits the return
statement, causing probe to continue (and eventually succeed) despite
the DMA controller not being registered. Add the missing return rc;.

Fixes: 2e1136acf8a8 ("dmaengine: omap-dma: fix dma_pool resource leak in error paths")
