This replaces all of the dprintk() macro calls to the zrdev_dbg(),
zrdev_info(), or zrdev_err() calls as appropriate. This allows for the
removal of the dprintk() macro from each file it is defined in, along
with removal of the module params that track the debugging level.
In the case that a debugging level was used in a comparison, this has
been replaced with checking the console level debugging and making a
decision from there. If the console debugging level is at least the
KERN_ debugging level equivalent, then the comparison will evaluate as
true.
There are a few instances where pr_debug() must be used over the
zrdev_dbg(). These occur in the module cleanup functions because there
should be no devices defined once we get to those modules, so we have no
devices to pass to zrdev_dbg().

When I compiled this patch series with smatch I got these warnings:
zoran/videocodec.c:45 videocodec_attach() warn: variable dereferenced before check 'master' (see line 40)
zoran/videocodec.c:115 videocodec_detach() warn: variable dereferenced before check 'codec' (see line 111)
zoran/videocodec.c:168 videocodec_register() warn: variable dereferenced before check 'codec' (see line 166)
zoran/videocodec.c:200 videocodec_unregister() warn: variable dereferenced before check 'codec' (see line 198)
And I also got this warning when checking the kerneldoc:
zoran/zoran.h:307: warning: This comment starts with '/**', but isn't a kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
Can you fix this and post a v3?
Thanks!
Hans
