[Alsa-devel] [PATCH] 0.9.7b doesn't compile with [p]ac series kernels

[Bernhard Rosenkraenzer]

Since the -[p]ac kernel patch series make tty counts atomic, ALSA's 
serialmidi.c fails to compile.

Patch attached; this breaks "normal" kernels though [guess we need a 
configure check for atomic tty->count; I haven't done that yet]
