[PATCH] aes-gcm-p10: Use the correct bit to test for P10

From: Michal Suchanek <hidden>
Date: 2024-11-06 12:10:24
Also in: linux-crypto, lkml
Subsystem: linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Michael Ellerman, Linus Torvalds

A hwcap feature bit is passed to cpu_has_feature, resulting in testing
for CPU_FTR_MMCRA instead of the 3.1 platform revision.

Fixes: c954b252dee9 ("crypto: powerpc/p10-aes-gcm - Register modules as SIMD")
Reported-by: Nicolai Stange <redacted>
Signed-off-by: Michal Suchanek <redacted>
