Subject: [PATCH] video: fbdev: Set pixclock = 0 in goldfishfb
Git-commit: ace6033ec5c356615eaa3582fb1946e9eaff6662
Patch-mainline: v4.19-rc1
References: bsc#1051510

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.
