v4l2_find_nearest_format is not useful for drivers in finding the best
matching format as it assumes a V4L2 specific struct. Drivers will use
v4l2_find_nearest_size instead.Signed-off-by: Sakari Ailus
Signed-off-by: Mauro Carvalho Chehab -
Add a function (as well as a helper macro) to obtain the best size in a
list of device specific sizes. This helps writing drivers as well as
aligns interface behaviour across drivers.The struct in which this information is contained in is typically specific
to the driver, therefore the existing function v4l2_find_nearest_format()
does not address the need.Signed-off-by: Sakari Ailus

This struct is there just two store two arguments of
v4l2_find_nearest_format(). The other two arguments are passed
as parameter.IMHO, there isn't much sense on doing that, and that will just
add one more struct to document ;)So, let's get rid of the struct, passing the parameters directly.

Currently, there's a mess at the V4L2 printk macros: some drivers
use their own macros, others use pr_foo() or v4l_foo() macros,
while more modern drivers use dev_foo() macros.The best is to get rid of v4l_foo() macros, as they can be
replaced by either dev_foo() or pr_foo(). Yet, such change can
be disruptive, as dev_foo() cannot use KERN_CONT. So, the best
is to do such change driver by driver.There are replacements for most v4l_foo() macros, but it lacks
a way to enable debug messages per level. So, add such macro,
in order to make the conversion easier.Signed-off-by: Mauro Carvalho Chehab
