Subject: lib/halfmd4.c: use rol32 inline function in the ROUND macro
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1c78bc170f393317dfa9d57baa599a51061ea86a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

lib/halfmd4.c: use rol32 inline function in the ROUND macro

<linux/bitops.h> provides rol32() inline function, let's use already
predefined function instead of direct expression.
