debugfs: Add debugfs_create_xul() for hexadecimal unsigned long

2019-11-03T17:08:53Z

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. Add a debugfs helper for "unsigned long" objects in hexadecimal format. This avoids the need for users to open-code the same, or introduce bugs when casting the value pointer to "u32 *" or "u64 *" to call debugfs_create_x{32,64}().

debugfs: remove return value of debugfs_create_atomic_t()

2019-11-03T13:03:01Z

No one checks the return value of debugfs_create_atomic_t(), as it's not needed, so make the return value void, so that no one tries to do so in the future. Link: https://lore.kernel.org/r/20191016130332.GA28240@kroah.com Signed-off-by: Greg Kroah-Hartman
