2013-04-04[media] mx2_camera: use module_platform_driver_probe()Fabio Porcedda
The commit 39793c6 "[media] mx2_camera: Convert it to platform driver" used module_platform_driver() to make code smaller, but since the driver used platform_driver_probe is more appropriate to use module_platform_driver_probe().

2013-03-31[media] s5p-fimc: Change the driver directory name to exynos4-isSylwester Nawrocki
The s5p-fimc directory now contains drivers for multiple IP blocks found in multiple Samsung application processors. This includes FIMC (CAMIF), MIPI CSIS and FIMC LITE. FIMC-IS (Imaging Subsystem) driver is going to be put into same directory. Hence we rename it to exynos4-is as s5p-fimc was only relevant for early version of this driver, when it only supported FIMC IP block. The imaging subsystem drivers for Exynos4 SoC series and S5PV210 will be included in drivers/media/platform/exynos4-is directory, with some modules shared with exynos5 series, while the rest of exynos5 specific modules will find their home in drivers/media/platform/exynos5-is.

2013-03-31[media] s5p-fimc: Ensure proper s_power() call order in the ISP datapathsSylwester Nawrocki
Since the FIMC-IS firmware communicates with an image sensor directly through the ISP I2C bus controllers the sub-devices power supplies cannot be simply enabled from left to right or disabled from right to left along the processing pipeline. Thus a subdev index to call s_power() on is looked up from a table, rather than doing the op call based on increasing/decreasing indexes.

In configurations where FIMC-LITE is used to capture image signal from an external sensor only we need to ensure one of FIMC devices is in active power state and the "fimc" gate clock is enabled.

2013-03-31[media] s5p-fimc: Add support for ISP Writeback data input bus typeSylwester Nawrocki
A second sink pad is added to each FIMC.N subdev that will be used to link it to the FIMC-IS-ISP subdev. Only V4L2_MBUS_FMT_YUV10_1X30 format is supported at this pad (FIMC_SD_PAD_SINK_FIFO). The routine checking for mismatch in the image formats at sides of the links is updated to account for the fact FIMC.X subdevs now have sink pads at the pad indexes 0, 1 and source pad at pad index 2. If link to FIMC.X pad 1 is activated we switch FIMC input data bus type to the ISP Writeback. Only a single active link to FIMC.X pad 0 or 1 will be allowed at any time.

We cannot assume that the passed entity the fimc_pipeline_prepare() function is supposed to start the media graph traversal from will always have its sink pad at pad index 0. Find the starting media entity's sink pad by iterating over its all pads and checking the pad flags.

2013-03-31[media] s5p-fimc: Add device tree based sensors registrationSylwester Nawrocki
The sensor (I2C and/or SPI client) devices are instantiated by their corresponding control bus drivers. Since the I2C client's master clock is often provided by a video bus receiver (host interface) or other than I2C/SPI controller device, the drivers of those client devices are not accessing hardware in their driver's probe() callback. Instead, after enabling clock, the host driver calls back into a sub-device when it wants to activate them. This pattern is used by some in-tree drivers and this patch also uses it for DT case. This patch is intended as a first step for adding device tree support to the S5P/Exynos SoC camera drivers. The second one is adding support for asynchronous sub-devices registration and clock control from sub-device driver level. The bindings shall not change when asynchronous probing support is added.

2013-03-29PNP: List Rafael Wysocki as a maintainerRafael J. Wysocki
The Adam Belay's e-mail address in MAINTAINERS under PNP SUPPORT is not valid any more and I started to maintain that code in the meantime as a matter of fact, so list myself as a maintainer of it along with Bjorn and remove the Adam's entry from it.

2013-03-29rbd: don't zero-fill non-image object requestsAlex Elder
A result of ENOENT from a read request for an object that's part of an rbd image indicates that there is a hole in that portion of the image. Similarly, a short read for such an object indicates that the remainder of the read should be interpreted a full read with zeros filling out the end of the request. This behavior is not correct for objects that are not backing rbd image data. Currently rbd_img_obj_request_callback() assumes it should be done for all objects. Change rbd_img_obj_request_callback() so it only does this zeroing for image objects. Encapsulate that special handling in its own function. Add an assertion that the image object request is a bio request, since we assume that (and we currently don't support any other types). This resolves a problem identified here: http://tracker.ceph.com/issues/4559 The regression was introduced by bf0d5f503dc11d6314c0503591d258d60ee9c944.

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs Pull btrfs fixes from Chris Mason: "We've had a busy two weeks of bug fixing. The biggest patches in here are some long standing early-enospc problems (Josef) and a very old race where compression and mmap combine forces to lose writes (me). I'm fairly sure the mmap bug goes all the way back to the introduction of the compression code, which is proof that fsx doesn't trigger every possible mmap corner after all. I'm sure you'll notice one of these is from this morning, it's a small and isolated use-after-free fix in our scrub error reporting.

Loading the cypress firmware is not dvb specific and should be common functionality. Move the source to media/common and make it a standalone module. As a result we can remove the dependency on dvb-usb in go7007, which has nothing to do with dvb.

2013-03-29Btrfs: don't drop path when printing out tree errors in scrubJosef Bacik
A user reported a panic where we were panicing somewhere in tree_backref_for_extent from scrub_print_warning. He only captured the trace but looking at scrub_print_warning we drop the path right before we mess with the extent buffer to print out a bunch of stuff, which isn't right. So fix this by dropping the path after we use the eb if we need to.
