• 783c2fb1b   FMC: fix locking in sample chardev driver ... Browse Code »

  The fmc-chardev module was over-locking, by calling misc
  register/unregister while holding its spinlock. This reported a
  "scheduling while atomic" error.

  Since the misc driver already serializes operations internally, this
  commit downgrades the fmc-chardev lock to just cover its own list.
