[PATCH] drivers_macintosh_via-pmu_.c

  As part of my work on the Linux Kernel Janitors project, cleaning up on
  functions which call misc_register and don't check for an error
  return, I would like to submit my patch to drivers/macintosh/via-pmu*.c.

  There is one call in each file which calls misc_register without checking
  the return value. The attached patch should fix that.
