Subject: USB: io_ti.c: remove unneeded null tty check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b56394bf325820e9f338eaef2941f18b17b98098;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

USB: io_ti.c: remove unneeded null tty check

The Coverity checker (and Adrian Bunk) spotted an inconsistent NULL check of
port->tty (it's blindly dereferenced later without the check).

Alan Cox confirmed the check can go.
