X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d9c563626d9a136636385209d59d0c4f16c4a7ab;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

USB: visor: termios bits

Visor has a huge complex routine which displays termios bits for debug
but doesn't do anything. Get the correct behaviour by removing it all
