    [media] v4l2-common: add a debug macro to be used with dev_foo() · a41231d5
    Mauro Carvalho Chehab authored
    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.
