crypto: crypto4xx - Replace bitwise OR with logical OR in crypto4xx_build_pd
Clang warns: drivers/crypto/amcc/crypto4xx_core.c:921:60: warning: operator '?:' has lower precedence than '|'; '|' will be evaluated first [-Wbitwise-conditional-parentheses] (crypto_tfm_alg_type(req->tfm) == CRYPTO_ALG_TYPE_AEAD) ? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^ drivers/crypto/amcc/crypto4xx_core.c:921:60: note: place parentheses around the '|' expression to silence this warning (crypto_tfm_alg_type(req->tfm) == CRYPTO_ALG_TYPE_AEAD) ? ^ ) drivers/crypto/amcc/crypto4xx_core.c:921:60: note: place parentheses around the '?:' expression to evaluate it first (crypto_tfm_alg_type(req->tfm) == CRYPTO_ALG_TYPE_AEAD) ? ^ ( 1 warning generated. It looks like this should have been a logical OR so that PD_CTL_HASH_FINAL gets added to the w bitmask if crypto_tfm_alg_type is either CRYPTO_ALG_TYPE_AHASH or CRYPTO_ALG_TYPE_AEAD. Change the operator so that everything works properly.
