struct i2o_message * msg, u32 context);
ARGUMENTS
- c

DESCRIPTION
This function is called in interrupt context only. If the reply reached
before the timeout, the i2o_exec_wait struct is filled with the message
and the task will be waked up. The task is now responsible for
returning the message m back to the controller! If the message reaches
us after the timeout clean up the i2o_exec_wait struct (including
allocated DMA buffer).
Return 0 on success and if the message m should not be given back to
the I2O controller, or >0 on success and if the message should be given
back afterwords. Returns negative error code on failure. In this case
the message must also be given back to the controller.
