Hello team, Recently I have noticed that there are many places in code where register_driver() is called with non-zero mode with file operation structures that have neither read nor write APIs implemented. For example "ret = register_driver(path, &opamp_fops, 0444, dev);" while opamp_fops has only "opamp_open", "opamp_close" and "opamp_ioctl" implemented. I made a PR to fix it https://github.com/apache/incubator-nuttx/pull/5347 and change mode from "0444" to "0000", but want to ask if anyone sees any drawback in such an approach? Maybe I'm missing something?
Best regards, Petro
