Hi Andy,

Thank you for your input.

I'm planning to have a incremental series: first introduce a local "dev" pointer, then convert the resource management to "devm_*", and finally replace the remaining error reporting with "dev_err_probe()".

This keeps each series focused and avoids introducing intermediate patterns such as:

   ret = dev_err_probe(dev, ret, ...);
   goto error;

Once the cleanup paths are removed, those sites naturally become:

   return dev_err_probe(dev, ret, ...);

Does this approach sound reasonable?

Yep, understood.

I'll revisit series, drop dead code and send v2.

Thanks, Sanjay
