[media] lbdt3306a: rework at printk macros
Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:

[media] lbdt3306a: rework at printk macros
Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:

[media] lbdt3306a: rework at printk macros
Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:

[media] lbdt3306a: rework at printk macros
Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:

[media] lbdt3306a: rework at printk macros
Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:

[media] lbdt3306a: rework at printk macros
Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:

Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:

[media] lbdt3306a: rework at printk macros
Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:

[media] lbdt3306a: rework at printk macros
Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:

[media] lbdt3306a: rework at printk macros
Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:

[media] lbdt3306a: rework at printk macros
Use pr_foo() where there's a direct replacement. For debug, use
custom-made macros, for now, as there are 3 different debug levels.
We should get rid of those some day, specially since several such
macros can be just removed, as Kernel trace would provide about
the same output.
This gets rid of some checkpatch errors:
