2014-03-11[media] vb2: change result code of buf_finish to voidHans Verkuil1-2/+2
The buf_finish op should always work, so change the return type to void. Update the few drivers that use it.

2014-03-05[media] v4l: Rename vb2_queue.timestamp_type as timestamp_flagsSakari Ailus1-1/+1
The timestamp_type field used to contain only the timestamp type. Soon it will be used for timestamp source flags as well. Rename the field accordingly.

2014-01-07[media] media: Remove OOM message after input_allocate_deviceJoe Perches1-1/+0
Emitting an OOM message isn't necessary after input_allocate_device as there's a generic OOM and a dump_stack already done. Signed-off-by: Joe Perches <[email protected]> Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2013-11-29[media] media_tree: Fix spelling errorsJonathan McCrohan1-1/+1
Fix various spelling errors in strings and comments throughout the media tree. The majority of these were found using Lucas De Marchi's codespell tool.

2013-05-07[media] pwc: Fix comment wrt lock orderingHans de Goede1-1/+1
With all the changes to handle the locking in the v4l2-core rather then at the driver level, the order in which the 2 pwc locks need to be taken has changed, update the comment in the header file to correctly reflect this.

2013-03-05[media] vb2: Add support for non monotonic timestampsKamil Debski1-0/+1
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.

2012-12-27[media] pwc: Replace memcpy with struct assignmentEzequiel Garcia1-1/+1
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 <[email protected]> Signed-off-by: Ezequiel Garcia <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>

2012-10-28[media] pwc-if: must check vb2_queue_init() successMauro Carvalho Chehab1-1/+5
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 <[email protected]>

2012-09-13[media] pwc: Remove unneeded struct vb2_queue clearingEzequiel Garcia1-1/+0
struct vb2_queue is allocated through kzalloc as part of a larger struct, there's no need to clear it. Cc: Hans de Goede <[email protected]> Signed-off-by: Ezequiel Garcia <[email protected]> Signed-off-by: Hans de Goede <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2012-09-13[media] pwc: Use vb2 queue mutex through a single nameEzequiel Garcia1-1/+1
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.

2012-08-16[media] Fix some Makefile rulesMauro Carvalho Chehab1-1/+1
On a few places, := were using instead of +=, causing drivers to not compile. While here, standardize the usage of += on all cases where multiple lines are needed, and for obj-y/obj-m targets, and := when just one line is needed, on <module>-obj rules.
