Hi Greg, Thus wrote Greg KH (greg@xxxxxxxxx): > That is because you have created a driver attribute, not a device > attribute. Create device attributes and you should be fine, they bind > to the device your driver is passed. could you point me to an example in the kernel tree where this is done correctly for a platform device? I had a look at http://kroah.com/log/blog/2013/06/26/how-to-create-a-sysfs-file-correctly/ but I couldn't figure out how to create device attributes in a simple platform driver that binds to a platform device. Thanks a lot for your help, Martin _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
