7885d2052bd9 drm/i915: mask transcoder select bits before
setting them on LVDS, 2012-01-12
for inclusion in the 3.2.y tree. Bisects to v3.2-rc1~135^2~2^2~17
("drm/i915: add PLL sharing support to handle 3 pipes") so 3.1.y and
earlier are not affected. Fixed between v3.3-rc1 and -rc2 so 3.3.y is
not affected, either.
Jakob (cc-ed) confirmed that the patch helps.
The author acked it for inclusion in stable.
