If we send a packet to the f/w, and that packet is unsupported, we want to be able to identify this situation and possibly ignore this. Therefore, if the f/w returned an error, we need to propagate it to the callers in the result value, if those callers were interested in it. In addition, no point of printing the error code here because each caller prints its own error with a specific message. Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
