Subject: crypto: aes-gcm-p10 - Use the correct bit to test for P10
X-Git-Tag: v6.13-rc1~196^2~4
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3574a5168ff3b6bddc4cd235878491f75967c8d4;p=thirdparty%2Fkernel%2Flinux.git

crypto: aes-gcm-p10 - Use the correct bit to test for P10

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