2015-04-08[media] Add and use IS_REACHABLE macroArnd Bergmann116-116/+125
In the media drivers, the v4l2 core knows about all submodules and calls into them from a common function. However this cannot work if the modules that get called are loadable and the core is built-in. In that case we get drivers/built-in.o: In function `set_type': drivers/media/v4l2-core/tuner-core.c:301: undefined reference to `tea5767_attach' drivers/media/v4l2-core/tuner-core.c:307: undefined reference to `tea5761_attach' drivers/media/v4l2-core/tuner-core.c:349: undefined reference to `tda9887_attach' drivers/media/v4l2-core/tuner-core.c:405: undefined reference to `xc4000_attach' This was working previously, until the IS_ENABLED() macro was used to replace the construct like #if defined(CONFIG_DVB_CX24110) || (defined(CONFIG_DVB_CX24110_MODULE) && defined(MODULE)) with the difference that the new code no longer checks whether it is being built as a loadable module itself. To fix this, this new patch adds an 'IS_REACHABLE' macro, which evaluates true in exactly the condition that was used previously. The downside of this is that this trades an obvious link error for a more subtle runtime failure, but it is clear that the change that introduced the link error was unintentional and it seems better to revert it for now. Also, a similar change was originally created by Trent Piepho and then reverted by teh change to the IS_ENABLED macro. Ideally Kconfig would be used to avoid the case of a broken dependency, or the code restructured in a way to turn around the dependency, but either way would require much larger changes here.

2015-04-08[media] xc5000: fix memory corruption when unplugging deviceDevin Heitmueller1-1/+4
This patch addresses a regression introduced in the following patch: commit 5264a522a597032c009f9143686ebf0fa4e244fb Author: Shuah Khan <shuahkh@osg.samsung.com> [media] media: tuner xc5000 - release firmwware from xc5000_release() The "priv" struct is actually reference counted, so the xc5000_release() function gets called multiple times for hybrid devices. Because release_firmware() was always being called, it would work fine as expected on the first call but then the second call would corrupt aribtrary memory. Set the pointer to NULL after releasing so that we don't call release_firmware() twice. This problem was detected in the HVR-950q where plugging/unplugging the device multiple times would intermittently show panics in completely unrelated areas of the kernel.

The system clock to IR is needed for the driver to communicate with the IR hardware via MMIO accesses on the system bus, so it must not be disabled during use or the driver will malfunction.

The slock spinlock in the cx23885_dev struct is only initialised if analogue video is being used, but is used in other places too, leading to the attached lockdep complaint. Move the lock initialisation so that it is done unconditionally. INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.

Removes some functions that are not used anywhere: s5p_jpeg_input_raw_y16() s5p_jpeg_timer_disable() s5p_jpeg_timer_enable(). This was partially found by using a static code analysis program called cppcheck.

2015-04-07[media] s5p-jpeg: Initialize jpeg_addr fields to zeroJacek Anaszewski1-2/+2
JPEG codecs on Exynos4 and Exynos3250 SoCs utilize different number of planes for storing the raw image data, depending on the format of the image being processed. For the unused planes a random data was being written to the related registers. Regardless of the fact that this seemed not to be harmful, fix the issue for clarity reasons.
