    Subject[PATCH 4.9 03/56] video: fbdev: Set pixclock = 0 in goldfishfb
    Date
    4.9-stable review patch.  If anyone has any objections, please let me know.

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

    [ Upstream commit ace6033ec5c356615eaa3582fb1946e9eaff6662 ]

    User space Android code identifies pixclock == 0 as a sign for emulation
    and will set the frame rate to 60 fps when reading this value, which is
    the desired outcome.
