Hi,
patch below replaces most uses of strtok by strsep. It compiles,
but otherwise it's untested.
This change is suggested by the Kernel Janitor TODO List because
strtok is not threadsafe. For most of the framebuffer drivers it
was already done. For some more information see lib/string.c:14.
Linus, please apply.
René
