ALSA: firewire-lib: fix invalid assignment to union data for directional parameter
[ Upstream commit 8304cf77c92038cd1c50c27b69d30be695cc8003 ] Although the value of FDF is used just for outgoing stream, the assignment to union member is done for both directions of stream. At present this causes no issue because the value of same position is reassigned later for opposite stream. However, it's better to add if statement.
