Both ts_release() and ts_open() can use "output" before check (smatch): drivers/media/pci/ddbridge/ddbridge-core.c:816 ts_release() warn: variable dereferenced before check 'output' (see line 809) drivers/media/pci/ddbridge/ddbridge-core.c:836 ts_open() warn: variable dereferenced before check 'output' (see line 828) Fix by performing checks on those pointers.

Smatch reported: drivers/media/pci/ddbridge/ddbridge-core.c:1602 dvb_input_attach() error: we previously assumed 'dvb->fe' could be null (see line 1595) dvb->fe2 will ever only be populated when dvb->fe is set.

While it seems valid that headers can carry simple oneline static inline annotated functions, move them into their own header file to have the overall code more readable. Also, keep them as header (and don't put in a separate object) and static inline to help the compiler avoid generating function calls. (Thanks to Jasmin J. <jasmin@anw.at> for valuable input on this!) Cc: Jasmin J. <jasmin@anw.at> Signed-off-by:

This huge patch bumps the ddbridge driver to version 0.9.29. Compared to the vendor driver package, DD OctoNET including GTL link support, and all DVB-C Modulator card support has been removed since this requires large changes to the underlying DVB core API, which should eventually be done separately, and, after that, the functionality/device support can be added back rather easy. While the diff is rather large, the bump is mostly a big refactor of all data structures. Yet, the MSI support (message signaled interrupts) is greatly improved, also all currently available CI single/duo bridge cards are fully supported. More changes compared to the upstream driver: - the DDB_USE_WORKER flag/define was removed, kernel worker functionality will be used. - coding style is properly fixed (zero complaints from checkpatch) - all (not much though) CamelCase has been fixed to kernel_case - (private) IOCTLs temporarily removed (which are mainly used to provide rarely-used FPGA update functionality) Great care has been taken to keep all previous changes and fixes (e.g. kernel logging via dev_*(), pointer annotations and such) intact. Permission to reuse and mainline the driver code was formally granted by Ralph Metzler <rjkm@metzlerbros.de>. Signed-off-by:

As of 0.9.9b, the ddbridge code has been split from one single file (ddbridge-core.c) into multiple files, with the purpose of taking care of different topics, and to be able to reuse code in different kernel modules (ddbridge.ko and octonet.ko). This applies the same code split, with a notable difference: In the vendor package, the split was done by moving all code parts into separate files, and in the "main" code files (ddbridge.c and octonet.c), a simple "#include ddbridge-core.c" was done. In this patch, the same split (codewise) is done, but all resulting .c/.o files will be handled by the makefile, with proper prototyping of all shared functions done in ddbridge.h. To avoid conflicts wrt the global space, the I2C functions and necessary prototypes for ddbridge-i2c.c are moved into ddbridge-i2c.h, which is to be included wherever required. Signed-off-by:

The functions in ddbridge-core.c have been moved to different positions in newer versions of the dddvb vendor driver package (most notably in version 0.9.9b). Perform the same code move to keep the diff of the upcoming code bump simpler. Signed-off-by:

Previously, possible digital gains were just 1x, 2x and 4x. These coarse gains were not sufficient in fine-tuning the image capture. Now, digital gain range is [0, 16x] with each step 1/1024, default 1x. This is achieved through OV13858 MWB R/G/B gain controls. Signed-off-by:

On format change, sometimes, sensor was streaming at a much higher FPS than the default. This was resulting in various problems like frame drops/corruption. Upon format change, set default vblank as current vblank. This will ensure that sensor will start streaming at default fps. Signed-off-by:

The Amlogic SoC embeds a standalone CEC controller, this patch adds a driver for such controller. The controller does not need HPD to be active, and could support up to max 5 logical addresses, but only 1 is handled since the Suspend firmware can make use of this unique logical address to wake up the device. The Suspend firmware configuration will be added in an other patchset. Signed-off-by:

Certain syscalls like recvmmsg support 64 bit timespec values for the X32 ABI. The helper function compat_put_timespec converts a timespec value to a 32 bit or 64 bit value depending on what ABI is used. The v4l2 compat layer, however, is not designed to support 64 bit timespec values and always uses 32 bit values. Hence, compat_put_timespec must not be used. Without this patch, user space will be provided with bad timestamp values from the VIDIOC_DQEVENT ioctl. Also, fields of the struct v4l2_event32 that come immediately after timestamp get overwritten, namely the field named id.

Commit b2787845 ("V4L/DVB (5289): Add support for video output overlays.") added the field global_alpha to struct v4l2_window but did not update the compat layer accordingly. This change adds global_alpha to struct v4l2_window32 and copies the value for global_alpha back and forth. Signed-off-by:

These can only be accessed with CAP_SYS_ADMIN so it's not a critical security issue. The problem is that "page" is controlled by the user in the ioctl(). The test to see if the bit is set in state->info->page_mask is not sufficient because "page" can be very high and shift wrap around to a bit which is set. Signed-off-by:

24 GPIO pins from 32 available on solo6x10 chips are exported to gpiolib. First 8 GPIOs are reserved for internal use on capture card boards, GPIOs in range 8:15 are configured as outputs to control relays, remaining 16:31 are configured as inputs to read sensor states. Now with this patch userspace DVR software can switch relays and read sensor states when GPIO extension cards are attached to Softlogic solo6x10 based video capture cards. Signed-off-by:
