Subject: [IPoIB] cleanups: fix comment, remove useless variables
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3bc12e75b23c0499cc2c0873a5f77494be173761;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[IPoIB] cleanups: fix comment, remove useless variables

Minor cleanups: fix a misleading comment, and get rid of attr_mask
variables that are only used to hold constants (just use the constants
directly).
