misc: bln: Cancel pending blinking/static light works on lights off

When the notification lights are turned off, be sure that there are
no more pending blinking/static light works.
[media] media: Init the reserved fields of struct media_link_desc

struct media_link_desc is copy_to_user'ed as the return value of
MEDIA_IOC_ENUM_LINKS. When copying, the driver is omitting to initialise
the reserved fields.  This commit fixes that by initialising the
reserved fields to 0.

power: don't wait for timeout if sys_sync completes early

In some cases the suspend thread is waiting for timer to expire
even if the sync workqueue is empty. So the suspend is taking extra
time.
To avoid this waiting, sending the completion event from
last sync item in workqueue.
