linux-next: ttydev tree build failure

linux-next: ttydev tree build failure

[Stephen Rothwell]

Hi Alan,

Today's linux-next build (powerpc ppc64_defconfig) failed like this:

drivers/char/hvc_console.c: In function 'hvc_set_winsz':
drivers/char/hvc_console.c:532: warning: passing argument 2 of 'tty_do_resize' from incompatible pointer type
drivers/char/hvc_console.c:532: error: too many arguments to function 'tty_do_resize'

Caused by commit eb6ab2d361a49470ca9785c70482772c19e49bec
("pty-simplify-resize") from the ttydev tree interacting with commit
febde3711992a64ea83a47a719f68a90c4b0927a ("hvc_console: Add support for
tty window resizing").

The former added another call to the function that the latter changed.

I applied the following patch.

Patch is correct.

Do the hvc patches have dependancies on the PPC tree as well as the tty
tree ?

Note that I have a serie of 5 hvc patches in the ppc tree...

In linux-next, the pty-simplify-resize patch has changed the
tty_do_resize() signature; and therefore the hvc patch did not compile.

The patch is correct.
Thanks.

The powerpc patches including these hvc_console patches have now gone
upstream to Linus' tree ...
