When occur i2c ack error, mtk_i2c_irq is called twice, first is the ack error interrupt, then the complete interrupt. i2c interrupt handler should keep the two interrupt value, and only call complete() for the complete interrupt. Signed-off-by: Liguo Zhang Signed-off-by: Eddie Huang

[PATCH 0/2] Mediatek I2C fixup

This series provide two patches to optimize mediatek i2c driver. The first patch will reset dma hardware in init function to make sure hardware work in good state. The second patch fix i2c interrupt handling for ACK error. All these patches base on v4.2-rc1. Eddie Huang (2): i2c: mediatek
