Subject: TTY: tty_io, remove buffer re-assignments
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=a8fbc974c347a798fd0c6f0bffe7bf46b8c6dfb6;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

TTY: tty_io, remove buffer re-assignments

TTY buffer head and tail are initialized in tty_buffer_init. No need
to do it once again in initialize_tty_struct where tty_buffer_init is
called.
