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
