Subject: Return a real error code and actual bytes written in SpiPacket.sendDone.
X-Git-Tag: release/2.1.0-1~3
X-Git-Url: https://oss.titaniummirror.com/gitweb/?p=tinyos-2.x.git;a=commitdiff_plain;h=56ef4a7cec43b0cca7a98ed616aadb4796e54625

Return a real error code and actual bytes written in SpiPacket.sendDone.

Be careful with this one.  The usart SPI peripheral always returned the length
it was given and an error of SUCCESS, so this could create some regressions.
