Subject: IB/core: Fix IB_SA_COMP_MASK macro
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=02daaf2741e74758a119768ca80cdf71c994ebd3;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

IB/core: Fix IB_SA_COMP_MASK macro

It needs parentheses around the argument, so that it can be used with
complex arguments (e.g., "n+5").
