| | | | | | | | | | | | | | usb_device_id are not supposed to change at runtime. All functions working with usb_device_id provided by <linux/usb.h> work with const usb_device_id. So mark the non-const structs as const. 'drivers/media/usb/b2c2/flexcop-usb.c' Fix checkpatch.pl error: ERROR: space prohibited before open square bracket '['.

* [media] usb: constify vb2_ops structuresJulia Lawall2016-09-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check for vb2_ops structures that are only stored in the ops field of a vb2_queue structure. That field is declared const, so vb2_ops structures that have this property can be declared as const also. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r disable optional_qualifier@ identifier i; position p; @@ static struct vb2_ops i@p = { ... }; @ok@ identifier r.i; struct vb2_queue e; position p; @@ e.ops = &i@p; @bad@ position p != {r.p,ok.p}; identifier r.i; struct vb2_ops e; @@ e@i@p @depends on !bad disable optional_qualifier@ identifier r.i; @@ static +const struct vb2_ops i = { ... }; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

* [media] vb2: replace void *alloc_ctxs by struct device *alloc_devsHans Verkuil2016-07-081-1/+1
| | | | | | | | | | | | | | | | Make this a proper typed array. Drop the old allocate context code since that is no longer used. Note that the memops functions now get a struct device pointer instead of the struct device ** that was there initially (actually a void pointer to a struct containing only a struct device pointer). This code is now a lot cleaner.

* [media] vb2: drop v4l2_format argument from queue_setupHans Verkuil2015-12-181-1/+0Star
| | | | | | | | | | | | | | | | | | | | | The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
