It seems that it's not a big C compiler implementation problem, because other drivers are using the bitfields in the uapi structures, too.

I see your reluctance to talk about extension of the bit field word, but perhaps, we may be clever and define the flag word for the newly added parameters now. The space may be used more precisely in the future with this change. Jaroslav -- Jaroslav Kysela <perex@xxxxxxxx> Linux Sound Maintainer; ALSA Project; Red Hat, Inc.
