I think we could rename it to crypto_crc32, but I don't think it's the only one. Marco, I think depmod should probably FAIL if two modules have the same name, which would at least find such problems.
This patch renames it to crc32_generic. ---8<--- Subject: crypto: crc32 - Rename generic implementation The generic crc32 implementation is currently called crc32. This is a problem because it clashes with the lib implementation of crc32. This patch renames the crypto crc32 to crc32_generic so that it is consistent with crc32c. An alias for the driver is also added. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
