The first patch fixes an incorrect errno returned by sanitize_name() when called with a NULL pointer. Returning ENOMEM in that case is misleading. EINVAL better reflects the actual error. The second patch switches sysfs show callbacks to sysfs_emit(), as recommended by Documentation/filesystems/sysfs.rst. While the risk of overflow with sprintf() is low in practice, using sysfs_emit() avoids the issue entirely and aligns the code with current kernel guidance. This also simplifies Rust bindings, where overflows cannot be ignored.
