"c77d17c0 [media] lirc: use-after free" introduces two problems: cdev_del() can be called with a NULL argument, and the kobject_put() path will cause a double free. Reported-by:

This patch changes the code for handling clocks. Now clocks are defined per each device variant, what is a preparation for adding support for Exynos 5433 MFC V8, which has more clocks than all previous versions. Also use devm_clk_get() to simplify cleanup path. Signed-off-by:

This patch moves preparation of clocks from s5p_mfc_init_pm() (driver probe) to s5p_mfc_power_on() (start of device operation). This change will allow to use runtime power usage optimization on newer Samsung Exynos platforms (for example Exynos 5433). Signed-off-by:

After commit "s5p-mfc: Fix clock management in s5p_mfc_release function" all clocks related functions are called only when MFC device is really available, so there is no additional check needed for NULL gate clocks. This patch simplifies the code and kills IS_ERR_OR_NULL macro usage. Signed-off-by:

We do video allocation all the time and we need it to be fast. Plus TLB efficiency isn't terribly important for video. That means we want to set DMA_ATTR_ALLOC_SINGLE_PAGES.

Zero is not a valid value for hsv_enc. Set the field to a valid initial value. This is not a problem for vivid, because it sets the field to 180 via tpg_s_hsv_enc() on the control initialization, but it might be a source of errors for other drivers that use this code. Signed-off-by:

The cec_allocate_adapter function doesn't need the parent device, only the cec_register_adapter function needs it. Drop the cec_devnode parent field, since devnode.dev.parent can be used instead. This change makes the framework consistent with other frameworks where the parent device is not used until the device is registered. Signed-off-by:

A recent cleanup had the right idea to remove the initialization of the error variable, but missed the actual benefit of that, which is that we get warnings if there is a bug in it. Now we get a warning about a bug that was introduced by this cleanup: drivers/media/platform/davinci/vpfe_capture.c: In function 'vpfe_probe': drivers/media/platform/davinci/vpfe_capture.c:1992:9: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized] This adds the missing initialization that the warning is about, and another one that was preexisting and that we did not get a warning for. That second bug has existed since the driver was first added.

Usually, I don't like fixing coding style issues on non-staging drivers, as it could be a mess pretty easy, and could become like a snow ball. That's the case of recent changes on two changesets: they disalign some statements. Yet, a care a lot with cx88 driver, as it was the first driver I touched at the Kernel, and I've been maintaining it since 2005. So, several of the coding style issues were due to my code. Per Andrey's suggestion, I ran checkpatch.pl in strict mode, with fixed several other issues, did some function alinments, but broke other alinments. So, I had to manually apply another round of manual fixes to make sure that everything is ok, and to make checkpatch happy with this patch. With this patch, checkpatch.pl is now happy when called with: ./scripts/checkpatch.pl -f --max-line-length=998 --ignore PREFER_PR_LEVEL Also, the 80-cols violations that made sense were fixed. Checkpatch would be happier if we convert it to use dev_foo(), but this is a more complex change. NOTE: there are some places with msleep(1). As this driver was written at the time that the default was to sleep at least 10ms on such calls (e. g. CONFIG_HZ=100), I replaced those calls by usleep_range(10000, 20000), with should be safe to avoid breakages. Fixes: 65bc2fe8 ("[media] cx88: convert it to use pr_foo() macros") Fixes: 7b61ba8f ("[media] cx88: make checkpatch happier") Suggested-by:

Commit 4710b752 ("[media] v4l: Add Renesas R-Car FDP1 Driver") in the v4l-dvb tree adds CONFIG_VIDEO_RENESAS_FDP1. It calls into the FCP driver, but when there is no dependency, FCP might be a module while FDP1 is built-in. We have the same logic in VIDEO_RENESAS_VSP1, which also depends on FCP not being a module when it is built-in itself. drivers/media/platform/rcar_fdp1.o: In function `fdp1_pm_runtime_resume': rcar_fdp1.c:(.text.fdp1_pm_runtime_resume+0x78): undefined reference to `rcar_fcp_enable' drivers/media/platform/rcar_fdp1.o: In function `fdp1_pm_runtime_suspend': rcar_fdp1.c:(.text.fdp1_pm_runtime_suspend+0x14): undefined reference to `rcar_fcp_disable' drivers/media/platform/rcar_fdp1.o: In function `fdp1_probe': rcar_fdp1.c:(.text.fdp1_probe+0x15c): undefined reference to `rcar_fcp_get' Signed-off-by:

It has never been possible to actually build this driver as a loadable module, only built-in because the Makefile attempts to build each file into its own module and fails: ERROR: "mbus_to_pix" [drivers/staging/media/davinci_vpfe/vpfe_video.ko] undefined! ERROR: "vpfe_resizer_register_entities" [drivers/staging/media/davinci_vpfe/vpfe_mc_capture.ko] undefined! ERROR: "rsz_enable" [drivers/staging/media/davinci_vpfe/dm365_resizer.ko] undefined!

It took a long time to catch this bug with randconfig builds because at least 14 other Kconfig symbols have to be enabled in order to configure this one, and it was clearly only ever tested as built-in with mainline kernels, if at all. The solution is really easy: this patch changes the Makefile to link all files into one module. As discussed previously, the driver has never before used successfully as a loadable module, but there is no reason to prevent that configuration.

In randconfig builds that select VIDEO_EM28XX_V4L2 and MEDIA_SUBDRV_AUTOSELECT, but not MEDIA_CAMERA_SUPPORT, we get a Kconfig warning: warning: (VIDEO_EM28XX_V4L2) selects VIDEO_MT9V011 which has unmet direct dependencies (MEDIA_SUPPORT && I2C && VIDEO_V4L2 && MEDIA_CAMERA_SUPPORT) This avoids the warning by making that 'select' conditional on MEDIA_CAMERA_SUPPORT.
