[PATCH v2 01/15] crypto: s390/sha3 - Rename conflicting functions

Eric Biggers ebiggers at kernel.org
Sat Oct 25 22:50:18 PDT 2025


From: David Howells <dhowells at redhat.com>

Rename the s390 sha3_*_init() functions to have an "s390_" prefix to
avoid a name conflict with the upcoming SHA-3 library functions.

Note: this code will be superseded later.  This commit simply keeps the
kernel building for the initial introduction of the library.
