The TDA1997x (HDMI receiver) driver currently uses a specific video format detection scheme. The frame (or field in interlaced mode), line and HSync pulse durations are compared to those of known, standard video modes. If a match is found, the mode is assumed to be detected, otherwise -ERANGE is returned (then possibly ignored). This means that: - another mode with similar timings will be detected incorrectly (e.g. 2x faster clock and lines twice as long) - non-standard modes will not work. This patch replaces this scheme with a direct read of geometry registers. This way all modes recognized by the chip are supported. In interlaced modes, the code assumes the V sync signal has the same duration for both fields. While this may be not necessarily true, I can't see any way to get the "other" V sync width. This is most probably harmless. All tests have been performed on Gateworks' Ventana GW54xx board, with a TDA19971 chip. Signed-off-by:

Newer clang versions are suspicious of definitions that mix concatenated strings with comma-separated arrays of strings, this has found real bugs elsewhere, but this seems to be a false positive: drivers/media/usb/gspca/gl860/gl860-mi1320.c:62:37: error: suspicious concatenation of string literals in an array initialization; did you mean to separate the elements with a comma?

I had a bit of a look around to find other configs that have the same problem, but could not come up with a reliable way and found nothing else through experimentation. It is likely that other symbols like these exist that need an extra select. Signed-off-by:

Adding kfree(dvb) to vidtv_bridge_remove() will remove the memory too soon: if an application still has an open filehandle to the device when the driver is unloaded, then when that filehandle is closed, a use-after-free access takes place to the freed memory. Move the kfree(dvb) to vidtv_bridge_dev_release() instead. Signed-off-by:

In dibusb_read_eeprom_byte(), if dibusb_i2c_msg() fails, val gets assigned an value that's not properly initialized. Using kzalloc() in place of kmalloc() for the buffer fixes this issue, as the val can now be set to 0 in the event dibusb_i2c_msg() fails.

mn88443x_cmn_power_on() did not handle possible errors of clk_prepare_enable() and always finished successfully so that its caller mn88443x_probe() did not care about failed preparing/enabling of clocks as well. Add missed error handling in both mn88443x_cmn_power_on() and mn88443x_probe(). This required to change the return value of the former from "void" to "int".

The SK Hynix Hi-846 is a 1/4" 8M Pixel CMOS Image Sensor. It supports usual features like I2C control, CSI-2 for frame data, digital/analog gain control or test patterns. This driver supports the 640x480, 1280x720 and 1632x1224 resolution modes. It supports runtime PM in order not to draw any unnecessary power. The part is also called YACG4D0C9SHC and a datasheet can be found at https://product.skhynix.com/products/cis/cis.go The large sets of partly undocumented register values are for example found when searching for the hi846_mipi_raw_Sensor.c Android driver.

Video driver maintains an internal context for the output buffer size. During S_fmt() on capture plane, the output buffer size is not updated in driver context. As a result, during buf_prepare(), the size of the vb2_plane and internal size of the buffer, as maintained by the driver, does not match. This leads to buf_prepare() failure. Update the instance context for the output buffer size during s_fmt(). Signed-off-by:
