* serial/arc-uart: Fix section mistmatchVineet Gupta2013-01-17
| | | | | | | | | | | | | | | | | | 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.

* TTY: switch tty_flip_buffer_pushJiri Slaby2013-01-16
| | | | | | | | | | | | | | | | | | | | 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: switch to devicetree based probingVineet Gupta2013-01-16
| | | | | | | | | | | | | | | | | | | * DT binding for arc-uart * With alll the bits in place we can now use DT probing. Note that there's a bit of kludge right now because earlyprintk portion of driver can't use the DT infrastrcuture to get resoures/plat_data. This requires some infrastructre changes to of_flat_ framework Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Grant Likely <grant.likely@secretlab.ca> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Alan Cox <alan@linux.intel.com> Cc: devicetree-discuss@lists.ozlabs.org Cc: Rob Herring <rob.herring@calxeda.com> Cc: Rob Landley <rob@landley.net> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* serial/arc-uart: split probe from probe_earlyprintkVineet Gupta2013-01-16
| | | | | | | | | | | | This is in preparation for devicetree based probing, where earlyprintk won't have access to DT serial aliases which the normal probe would absolutely rely on.

* serial/arc-uart: Don't index with -ve platform_device->idVineet Gupta2013-01-16
| | | | | | | | | | | | | | | probe routine could index into port[] with -ve index. The check in arc_uart_init_one() was too late. This came to light when trying to port driver to CONFIG_OF, where bydefault of-core code sets -ve platform dev id and in absence of DT serial aliases, driver would use the -ve index.
