Subject: [PATCH 2/3] dmaengine: stm32-mdma: fix chan initialization in stm32_mdma_irq_handler()
Date: Wed, 4 May 2022 17:53:21 +0200	[thread overview]
Message-ID: <20220504155322.121431-3-amelie.delaunay@foss.st.com> (raw)
In-Reply-To: <20220504155322.121431-1-amelie.delaunay@foss.st.com>

The parameter to pass back to the handler function when irq has been
requested is a struct stm32_mdma_device pointer, not a struct
stm32_mdma_chan pointer.
Even if chan is reinit later in the function, remove this wrong
initialization.

Fixes: a4ffb13c8946 ("dmaengine: Add STM32 MDMA driver")
