Subject: Re: [PATCH v8 04/14] media: platform: Change the fixed device node
 number to unfixed value

Thanks for the patch. The change is correct, but I think the commit
message doesn't really explain the real reason for it. Perhaps something
like

"The driver can be instantiated multiple times, e.g. for a decoder and
an encoder. Moreover, other drivers could coexist on the same system.
This makes the static video node number assignment pointless, so switch
to automatic assignment instead."

WDYT?

Best regards,
Tomasz
