        src/sys/external/bsd/drm2/linux: linux_wait_bit.c

Log Message:
linux: Fix wait_bit semantics.

- wait_on_bit is supposed to wait until the bit is cleared, not set.

- wait_on_bit_timeout is supposed to return 0 on success, -EAGAIN on
  faiure.

Omit wake_up_bit; nothing uses it and clear_and_wake_up_bit is a more
semantically coherent operation.
