Crypto/chcr: fix for ccm(aes) failed test
The ccm(aes) test fails when req->assoclen > ~240bytes. The problem is the value assigned to auth_offset is wrong. As auth_offset is unsigned char, it can take max value as 255. So fix it by making it unsigned int. Signed-off-by: Ayush Sawal <ayush.sawal@chelsio.com> Signed-off-by: Devulapally Shiva Krishna <shiva@chelsio.com> Signed-off-by: David S.
