Just a reminder, I'm just making suggestions, there is no strict action required
here other then a discussion to try and make the logging a bit more light.
My points was that C macros don't care about types, so if you keep the path to
the platform device the same (ctx->dev->plat_dev), you could just pass the ctx
as argument. What I don't know though myself, is if this is actually feasible in
all code path, but considering you had access to the instance previously, I
thought it should.
