Subject: [PATCH 2/2] spi: atmel: Add missing annotation for atmel_spi_next_xfer_dma_submit()
Date: Wed, 29 Apr 2020 23:57:23 +0100	[thread overview]
Message-ID: <20200429225723.31258-3-jbi.octave@gmail.com> (raw)
In-Reply-To: <20200429225723.31258-1-jbi.octave@gmail.com>

Sparse reports a warning at atmel_spi_next_xfer_dma_submit()

warning: context imbalance in atmel_spi_next_xfer_dma_submit()
	- unexpected unlock

The root cause is the missing annotation
	at atmel_spi_next_xfer_dma_submit()

Add the missing __must_hold(&as->lock) annotation
