Andrew Lunn 2d16161a2c i2c: imx: Only DMA messages with I2C_M_DMA_SAFE flag set ... [ Upstream commit d36678f790 ] Recent changes to the DMA code has resulting in the IMX driver failing I2C transfers when the buffer has been vmalloc. Only perform DMA transfers if the message has the I2C_M_DMA_SAFE flag set, indicating the client is providing a buffer which is DMA safe. This is a minimal fix for stable. The I2C core provides helpers to allocate a bounce buffer. For a fuller fix the master should make use of these helpers.
