-Subject: [PATCH] avr32: balance cpu_idle_poll_ctrl calls
-
-Since commit 01426478df3a8791ff5c8b6b82d409e699cfaf38
-(avr32: Use generic idle loop) the kernel throws the
-following warning on avr32:

-
-When the 'avr32_comparator' clockevent device is registered,
-the clockevent core sets the mode of that clockevent device
-to CLOCK_EVT_MODE_SHUTDOWN. Due to this, the 'comparator_mode'
-function calls the 'cpu_idle_poll_ctrl' to disables idle poll.
-This results in the aforementioned warning because the polling
-is not enabled yet.
-
-Change the code to only disable idle poll if it is enabled by
-the same function to avoid the warning.
