Merge tag 'crc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux

Pull CRC updates from Eric Biggers:
 "Cleanups for the kernel's CRC (cyclic redundancy check) code:

   - Use __ro_after_init where appropriate

   - Remove unnecessary static_key on s390

   - Rename some source code files

   - Rename the crc32 and crc32c crypto API modules

   - Use subsys_initcall instead of arch_initcall

   - Restore maintainers for crc_kunit.c

   - Fold crc16_byte() into crc16.c

   - Add some SPDX license identifiers"
