Subject: batman-adv: Remove uses of return value of seq_printf
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6d91147d183c87d290f3b062d3fbf1ede312b449;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

batman-adv: Remove uses of return value of seq_printf

This function is soon going to return void so remove the
return value use.

Convert the return value to test seq_has_overflowed() instead.
