+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.
