Subject: altos: Set SPI fill value each time it is used.
X-Git-Tag: 1.0.9.4~81
X-Git-Url: https://git.gag.com/?p=fw%2Faltos;a=commitdiff_plain;h=2bce71eba9f44b6fcf64e307c8174824c3a0fb57

altos: Set SPI fill value each time it is used.

This ensures that the final MOSI pin value will be high after a
receive is finished.
