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.
