Third release-candidate for 0.16.3 -- please test!

[Nicolas Boullis]

Hi,

Here is a the third release candidate for em8300 0.16.3. It fixes a
problem discovered by Antoine Pardigon with the model sysfs file: the
kernel oopsed when trying to read this file, because of a pointer to a
local (stack) array being passed to the adv717x driver (accross
modules).

The tarball is available on the usual location:
  http://dxr3.sourceforge.net/download/em8300-0.16.3-rc3.tar.gz


As usual, all comments are welcome.

Please give it a try and report.

Cheers,

Nicolas

Hello,

I tried to compile it with 2.6.23-rc2 and it doesn't work.
With 2.6.23-rc1 it was still working.

Thanks for the information.
It really sucks a lot: some work for every kernel release...
Anyway, I'd rather try to release 0.16.3 that supports kernels up to
2.6.22 and care about 2.6.23 for the next release...


Cheers,

Nicolas
