See what happens when you use dev_name(musb); Do you not think about the other users of this driver ? Do you not know what's the ID on platform_devices which "don't have an ID" ?? The drivers core set it to -1, then on everybody who's got a single musb instance, will have to access the "musb-1" directory. That doesn't seem nice. Just use dev_name(musb). > if (!root) { > ret = -ENOMEM; > goto err0; > } > > - file = debugfs_create_file("regdump", S_IRUGO, root, musb, > + sprintf(name, "regdump%d", musb->id); > + file = debugfs_create_file(name, S_IRUGO, root, musb, > &musb_regdump_fops); > if (!file) { > ret = -ENOMEM; > goto err1; > } > > + sprintf(name, "testmode%d", musb->id); this is unnecessary!! Only the directory name needs this trick, whatever's under the root directory does not need any ID appended to it. -- balbi
