free dnl data in i915 driver
Comment 2 haihao 2006-10-31 23:32:50 UTC 
After a new vertex program string is parsed, The driver should call
_tnl_program_string to free any existing tnl data. So this patch add a line
"_tnl_program_string(ctx, target, prog);" in ii915_fragprog.c/915ProgramStringNotify

Looks good, I've committed the patch.
Comment 4 Gordon Jin 2006-11-02 01:35:26 UTC 
Verified. Thanks for Keith's committing.

Mass version move, cvs -> git
