Subject: aarch64: Fix integral_init4/8h_neon
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=5c4728d8dd82ba46901824470db1609ae0f2521d;p=x264

aarch64: Fix integral_init4/8h_neon

The stride is the number of uint16_t elements and thus needs
to be shifted.

This issue had slipped unnoticed since checkasm didn't actually
verify the output of these functions.
