[PATCH 0/7] debugfs: Add and use debugfs_create_xul()

[Geert Uytterhoeven]

	Hi all,

The existing debugfs_create_ulong() function supports objects of
type "unsigned long", which are 32-bit or 64-bit depending on the
platform, in decimal form.  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!
