  Documentation/staging: Fix typo and incorrect citation in crc32.rst (2025-08-20 23:53:32 -0400)

----------------------------------------------------------------

Update crc_kunit to test the CRC functions in softirq and hardirq
contexts, similar to what the lib/crypto/ KUnit tests do. Move the
helper function needed to do this into a common header.

This is useful mainly to test fallback code paths for when
FPU/SIMD/vector registers are unusable.

----------------------------------------------------------------
Eric Biggers (4):
      kunit, lib/crypto: Move run_irq_test() to common header
      lib/crc: crc_kunit: Test CRC computation in interrupt contexts
      lib/crc: Use underlying functions instead of crypto_simd_usable()
      lib/crc: Drop inline from all *_mod_init_arch() functions
