WARNING: drivers/net/3c59x.o - Section mismatch: reference to .init.text: from .text between 'vortex_eisa_probe' (at offset 0x458c) and 'vortex_eisa_remove'

Fixed by:

 o move definition of vortex_eisa_driver below the functions it references.
 o remove now unnecessary prototypes for vortex_eisa_probe and
   vortex_eisa_remove.
 o Make vortex_eisa_probe an __init function.
 o Make vortex_eisa_remove a __devexit function.
 o Wrap vortex_eisa_driver reference to vortex_eisa_remove with
   __devexit_p().
