As reported by smatch: drivers/media/i2c/saa717x.c:155 saa717x_read() warn: mask and shift to zero drivers/media/i2c/saa717x.c:155 saa717x_read() warn: mask and shift to zero This is done right at saa717x_write(), but the read function is broken. Thankfully, there's just one place at saa717x driver that uses multibyte read (for status report, via printk). Yet, let's fix it. From saa717x_write(), it is clear that the bytes are in little endian: mm1[4] = (value >> 16) & 0xff; mm1[3] = (value >> 8) & 0xff; mm1[2] = value & 0xff; So, the same order should be valid for read too.

Instead of parsing the link-frequencies property in the driver, let v4l2_of_alloc_parse_endpoint() do it. Signed-off-by:
Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by:

Sakari Ailus authored
The link-frequencies property is a variable length array of link frequencies in an endpoint. The array is needed by an increasing number of drivers, so it makes sense to add it to struct v4l2_of_endpoint. However, the length of the array is variable and the size of struct v4l2_of_endpoint is fixed since it is allocated by the caller. The options here are 1. to define a fixed maximum limit of link frequencies that has to be the global maximum of all boards. This is seen as problematic since the maximum could be largish, and everyone hitting the problem would need to submit a patch to fix it, or 2. parse the property in every driver. This doesn't sound appealing as two of the three implementations submitted to linux-media were wrong, and one of them was even merged before this was noticed, or 3. change the interface so that allocating and releasing memory according to the size of the array is possible. This is what the patch does. v4l2_of_alloc_parse_endpoint() is just like v4l2_of_parse_endpoint(), but it will allocate the memory resources needed to store struct v4l2_of_endpoint and the additional arrays pointed to by this struct. A corresponding release function v4l2_of_free_endpoint() is provided to release the memory allocated by v4l2_of_alloc_parse_endpoint(). In addition to this, the link-frequencies property is parsed as well, and the result is stored to struct v4l2_of_endpoint field link_frequencies. Signed-off-by:
