X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0cee6bbe06f67ff7dd83a4bc794f23c5cd5e7929;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

tipc: remove unnecessary variables and conditions

We remove a number of unnecessary variables and branches
in TIPC. This patch is cosmetic and does not change the
operation of TIPC in any way.
