TTY: switch tty_flip_buffer_push Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push. IOW we also closed all the races in drivers not using tty_port_tty_get at all yet. Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.

serial/arc-uart: Fix section mistmatch Commit "serial/arc-uart: split probe from probe_earlyprintk" introduced a build time warning: "WARNING: vmlinux.o(.data+0x5baa0): Section mismatch in reference from the variable early_arc_platform_driver to the function .init.text:arc_serial_probe_earlyprintk()" While at it - fixed another incorrectly placed initdata annotation.
