Commit 31865c4c ("crypto: skcipher - Add lskcipher") moved some
fields from 'struct skcipher_alg' into SKCIPHER_ALG_COMMON but didn't
remove the corresponding kerneldoc members, which results in these
warnings when running 'make htmldocs':

  ./include/crypto/skcipher.h:182: warning: Excess struct member 'min_keysize' description in 'skcipher_alg'
  ./include/crypto/skcipher.h:182: warning: Excess struct member 'max_keysize' description in 'skcipher_alg'
  ./include/crypto/skcipher.h:182: warning: Excess struct member 'ivsize' description in 'skcipher_alg'
  ./include/crypto/skcipher.h:182: warning: Excess struct member 'chunksize' description in 'skcipher_alg'
  ./include/crypto/skcipher.h:182: warning: Excess struct member 'stat' description in 'skcipher_alg'
  ./include/crypto/skcipher.h:182: warning: Excess struct member 'base' description in 'skcipher_alg'

SKCIPHER_ALG_COMMON already has the documentation for all these fields.
