Simple suggestion for a make target

Simple suggestion for a make target

[Tom Watson]

Since it appears that frequently the kernel source has older versions of alsa
when released, wouldn't it be wise to have a target in the alsa-driver-xx.yy.z
directory that finds the kernel sources, and updates them.  Then one could
re-compile the kernel and all would be well with the world.

For those who don't wish to do this, the "./configure;make;make install"
sequence would work as well.

I suspect that the kernel configuration would pass thru, so one wouldn't need
to configure before "transferring" sources, but not being an expert, I don't
know.

Maybe this would encourage distrubutions that diddle with the kernel source to
have an up-to-date alsa.

Just an idea.

What would be the point?  It's already simpler than that.
Just ./configure && make && make install in alsa-driver directory to
install a newer ALSA.  It just overwrites the old ALSA modules that came
with the kernel with the newer ones.  You don't even need to reboot.

I see merits of providing kernel code (especially about the
distribution), but there are a few problems if we really do it.

- The alsa-kernel code base is kept for the very latest linux-kernel, 
  usually mm tree or Linus git tree.
- The codes for stable kernel tree need backward-compatiblity
  patches.

A typical example is the recent introduction of kzalloc().  This won't
work on 2.6.12 kernels.  That's how alsa-driver requires configure and
many hacks in its local tree.

Remember that the patch to the latest version can be obtained from
ALSA git tree, too.
