media: davinci/vpfe_capture.c: Avoid BUG_ON for register failure

2020-01-09T13:41:41+00:00

In vpfe_register_ccdc_device(), failure to allocate dev->hw_ops fields calls BUG_ON(). This patch returns the error to callers instead of crashing. The issue was identified by a static analysis tool, written by us. Signed-off-by: Aditya Pakki Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

remove ioremap_nocache and devm_ioremap_nocache

ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig Acked-by: Arnd Bergmann

media: use the BIT() macro

2019-08-26T17:08:50+00:00

As warned by cppcheck: [drivers/media/dvb-frontends/cx24123.c:434]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour [drivers/media/pci/bt8xx/bttv-input.c:87]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour [drivers/media/pci/bt8xx/bttv-input.c:98]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour ... [drivers/media/v4l2-core/v4l2-ioctl.c:1391]: (error) Shifting signed 32-bit value by 31 bits is undefined behaviour There are lots of places where we're doing 1 << 31. That's bad, as, depending on the architecture, this has an undefined behavior. The BIT() macro is already prepared to handle this, so, let's just switch all "1 << number" macros by BIT(number) at the header files with has 1 << 31.

media: v4l2-async: Get fwnode reference when putting it to the notifier's list

2019-07-25T12:01:43+00:00

The v4l2_async_notifier_add_fwnode_subdev() did not take a reference of the added fwnode, relying on the caller to handle that instead, in essence putting the fwnode to be added if there was an error. As the reference is eventually released during the notifier cleanup, this is not intuitive nor logical. Improve this by always getting a reference when the function succeeds, and the caller releasing the reference when it does not *itself* need it anymore. Luckily, perhaps, there were just a handful of callers using the function. Signed-off-by: Sakari Ailus Reviewed-by: Jacopo Mondi Tested-by: Niklas Söderlund Signed-off-by: Mauro Carvalho Chehab

media: davinci-vpif: Don't dereference endpoint after putting it, fix refcounting

2019-07-25T12:01:10+00:00

The davinci-vpif driver dereferences its local endpoints after releasing the reference to them. The driver also puts its endpoints explicitly while the of_graph_get_next_endpoint() does that, too, leading to obtaining a reference once and releasing it twice. Both are fixed by this patch.

media: drivers/media: don't set pix->priv = 0

2019-07-23T12:48:33+00:00

The priv field of struct v4l2_pix_format shouldn't be set by drivers, it's set by the v4l2 core instead to V4L2_PIX_FMT_PRIV_MAGIC. Drop this from the few media drivers that still do this. Note that the gspca patch is slightly more involved since some of the sub-gspca drivers use the priv field internally.
