Subject: [PATCH] media: bcm2835-unicam: Disable event-related ioctls
|
|
on metadata node
|
|
|
|
The unicam driver supports both the SOURCE_CHANGE and CTRL events. Both
|
|
events are only generated on the image video node, so the event-related
|
|
ioctls are useless on the medatada node. Disable them.
