Subject: char: synclink: Remove WARN_ON for bad port count
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=69fee6885f6042d0d3d3773b208a84e7bb161650;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

char: synclink: Remove WARN_ON for bad port count

tty_port_close_start() already validates the port counts and issues
a diagnostic if validation fails.
