[PATCH 06/13] crypto: x86/ghash - use u8 rather than char

From: Robert Elliott
Date: Mon Dec 19 2022 - 17:04:28 EST


Use more consistent unambivalent types (u8 rather than char)
for the source and destination buffer pointer arguments for
the asm functions.

Reference them with "asmlinkage" as well.
