[PATCH] strtok --> strsep in framebuffer drivers, last pieces (really!)

[René Scharfe]

Hi,

this seems to be the really last patch regarding `strtok in framebuffer
drivers'. It removes another compiler warning, converts the last three
strtok()s to strsep()s and in two cases adds `skip empty tokens'-code.
Please, apply.

René
