Subject[PATCH 24/30] dmaengine: mic_x100_dma: Add missing annotation for mic_dma_tx_submit_unlock()
Date
Sparse reports a warning dma_cookie_t mic_dma_tx_submit_unlock()

warning: context imbalance in mic_dma_tx_submit_unlock()
- unexpected unlock

The root cause is the missing annotation at mic_dma_tx_submit_unlock()
Add the missing annotation __releases(&mic_ch->prep_lock)
