[PATCH] i2c: qcom-geni: Fix GPI DMA buffer sync-back

2022-08-07 Thread Robin Reckmann
Fix i2c transfers using GPI DMA mode for all message types that do not set the I2C_M_DMA_SAFE flag (e.g. SMBus "read byte"). In this case a bounce buffer is returned by i2c_get_dma_safe_msg_buf(), and it has to synced back to the message after the transfer is done. Add missing assignment of dma b
