To format objects in hexadecimal, various debugfs_create_x*() functions exist, but all of them take fixed-size types. To work around this, some drivers call one of debugfs_create_x{32,64}(), depending on the size of unsigned long. Other driver just cast the value pointer to "u32 *" or "u64 *", introducing portability bugs or data leaks in the process. Hence this patch series adds a debugfs helper for "unsigned long" objects in hexadecimal format, and converts drivers to make use of it. It also contains two cleanups removing superfluous casts, which I added to this series to avoid conflicts. Thanks for your comments!
