* [media] vb2: Add support for non monotonic timestampsKamil Debski2013-03-05
| | | | | | | | | | | | | | | | Not all drivers use monotonic timestamps. This patch adds a way to set the timestamp type per every queue. In addition, set proper timestamp type in drivers that I am sure that use either MONOTONIC or COPY timestamps. Other drivers will correctly report UNKNOWN timestamp type instead of assuming that all drivers use monotonic timestamps.

* [media] pwc: Replace memcpy with struct assignmentEzequiel Garcia2012-12-27
| | | | | | | | | | | | | | | | | | | | | | | This kind of memcpy() is error-prone. Its replacement with a struct assignment is prefered because it's type-safe and much easier to read. Found by coccinelle. Hand patched and reviewed. Tested by compilation only. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier struct_name; struct struct_name to; struct struct_name from; expression E; @@ -memcpy(&(to), &(from), E); +to = from; // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com> Signed-off-by: Ezequiel Garcia <elezegarcia@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | drivers/media/usb/pwc/pwc-if.c: In function 'usb_pwc_probe': drivers/media/usb/pwc/pwc-if.c:1003:16: warning: ignoring return value of 'vb2_queue_init', declared with attribute warn_unused_result [-Wunused-result] In the past, it used to have a logic there at queue init that would BUG() on errors. This logic got removed. Drivers are now required to explicitly handle the queue initialization errors, or very bad things may happen. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | struct vb2_queue is allocated through kzalloc as part of a larger struct, there's no need to clear it.

| | | | | | | | | | | | This lock was being taken using two different names (pointers) in the same function. Both names refer to the same lock, so this wasn't an error; but it looked very strange.
