Subject: [PATCH] crypto: inside-secure - keep ivsize for DES ECB modes at 0
Git-commit: 36160aadb1034787d4d30b6af7805cb3dd636aac
References: jsc#SLE-14454
Patch-mainline: v5.4-rc1
The driver incorrectly advertised the IV size for DES and 3DES ECB
mode as being the DES blocksize of 8. This is incorrect as ECB mode
does not need any IV.
