Subject: [PATCH v1 0/4] initramfs: get rid of custom hex2bin()

The series that introduced simple_strntoul() had passed into kernel
without proper review and hence reinvented a wheel that's not needed.
Here is the refactoring to show that. This is assumed to go via PRINTK
tree.

I have tested this on x86, but I believe the same result will be
on big-endian CPUs (I deduced that from how strtox() works).

Andy Shevchenko (4):
  initramfs: Sort headers alphabetically
  initramfs: Refactor to use hex2bin() instead of custom approach
  vsprintf: Revert "add simple_strntoul"
  kstrtox: Drop extern keyword in the simple_strtox() declarations
