Subject: [PATCH 3.16.y-ckt 120/254] drm/nouveau/gpio: rename g92 class to g94

3.16.7-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Emil Velikov <emil.l.velikov@...il.com>

commit b485a7005faba38286bc02ab1d80e2cbf61c1002 upstream.

nv92 hardware has only 16 interrupt lines, while nv94 and later
has 32. Accessing 0xe0c{0,4} registers on nv92 can lead to incorrect
PDISP setup. This is a regression introduced with

commit 9d0f5ec9ee0fd5dc5fc1cc2cf559286431e406e3
Author: Ben Skeggs <bskeggs@...hat.com>
Date:   Mon May 12 15:22:42 2014 +1000

    gpio: split g92 class from nv50
