Hans Verkuil 0d5e8c4313 [media] Fix 64-bit division fall-out from 64-bit control ranges
Commit 0ba2aeb6da increased the internal control ranges
to 64 bit, but that caused problems in drivers that use the minimum/maximum/step/default_value
control values in a division or modulus operations since not all architectures support
those natively.

Luckily, in almost all cases it is possible to just cast to 32 bits (the control value
is known to be 32 bits, so it is safe to cast). Only in v4l2-ctrls.c was it necessary to
use do_div in one function.

Jean Delvare 877ed14306 [media] Prefer gspca_sonixb over sn9c102 for all devices
The sn9c102 driver is deprecated. It was moved to staging in
anticipation of its removal in a future kernel version. However, USB
devices 0C45:6024 and 0C45:6025 are still handled by sn9c102 when
both sn9c102 and gspca_sonixb are enabled.

We must migrate all the users of these devices to the gspca_sonixb
driver now, so that it gets sufficient testing before the sn9c102
driver is finally phased out.

Andy Shevchenko ee35fa2267 [media] gspca: print small buffers via %*ph
Instead of passing each byte through stack let's use %*ph specifier to do this
job better.

Ondrej Zary 1966bc2a48 [media] gspca: store current mode instead of individual parameters
Store complete current mode (struct v4l2_pix_format) in struct gspca_dev
instead of separate pixfmt, width and height parameters.
This is a preparation for variable resolution support.

Hans de Goede 0391dc17bd [media] gspca-sonixb: Adjust hstart on sn9c103 + pas202
For some unknown reason we need to increase hstart by 1 on when using the
PAS202 on the sn9c103 (versus on the sn9c102), otherwise we get the wrong
colors, due to shifting of the bayer pattern.

Hans de Goede 18fa0d36ad [media] gspca_sonixb: Properly wait between i2c writes
We must wait for the previous i2c write to complete before starting a new
one. Sofar we were getting away with this, but it seems that some parts
of the usb-subsystem has been sped up making us go to fast :)
This fixes streaming on sn9c103 based cams not working with an
"i2c_w error" error.
