Title:
  divide by zero error in radeon_surface.c when opening chrome with
  WebGL enabled

Status in “libdrm” package in Ubuntu:
  New

Bug description:
  Passing a tile_split of zero to eg_surface_init_2d causes a divide by
  zero error. Launching chromium with WebGL enabled on a AMD Llano
  (A8-3850) exhibits this behavior and webgl then fails to work. The
  attached patch fixes the problem and allows WebGL to work in chrome on
  this platform.

  Additional information:

  lsb_release -rd
  Description:	Ubuntu 13.10
  Release:	13.10

  Package version: 
  libdrm_2.4.46-1ubuntu1
