Is there a reason that the makefile rule below prevents creating .ver
files if there is a .c file with exports in the kernel with the same
name? (this happens for ac97_codec.c and sb_common.c)
Without .ver files, the make dependencies get out of whack, and the
affected .o files are rebuilt in each make run, even when they're up
to date.
As far as I can see, the kernel's and ALSA's .ver files could coexist
without problems, as they get their own directory, and don't (try to)
access each other.
Regards,
Clemens
