Can I get a justification for this change? On my boards, the CS4270 driver is compiled in-kernel, not as a module, and so when the kernel boots, the driver announces itself when it's loaded. I like this a lot, which is why I always put a pr_info() in the __init function of my modules.
It's rather chatty, especially where one has unused modules compiled into the kernel, and displayed on the (usually slow serial) console by default. Having lots of drivers announce themselves in this fashion gets rather spammy, at the minute only a very small proportion do so. As a matter of policy Linux drivers generally don't do this.
Printing a message when the driver is actually binding to hardware can be useful, mainly if it's something like announcing the device revision, but doing so at module load isn't really conveying anything meaningful.
