If this is single patch, I'd like to write the patch subject as "Documentation: sysfs: document HP-specific firmware attributes". And also, adjust the patch description accordingly, since as it is written above, it looks like general documentation of HP-specific feature (which should be in actual diff). > Version 7 > Includes only sysfs-class-firmware-attributes documentation Where is the rest of patches if this is a series? Had they been merged? Thanks. -- An old man doll... just what I always wanted! - Clara
