As wait_for_completion_interruptible_timeout() will be invoked after the first call to i2c_dw_xfer_msg() is made whether or not an error is detected in it, we need to mark ->cmd_complete as completed to avoid a needless HZ timeout. Signed-off-by: Shinya Kuribayashi <[email protected]> --- Or we could change the i2c_dw_xfer_msg() prototype from "void" to "int".
