In the (very) small print of the REPORT_CURRENT_LATENCY message there is a line that says that the last byte of the message (audio out delay) is only present if the 'audio out compensated' value is 3. I missed this, and so if this message was sent with a total length of 6 (i.e. without the audio out delay byte), then it was rejected by the framework since a minimum length of 7 was expected. Fix this minimum length check and update the wrappers in cec-funcs.h to do the right thing based on the message length. 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:

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:

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:
