Joel Stanley b4a6aaeaf4 drm/aspeed: Fix vga_pw sysfs output ... Before the drm driver had support for this file there was a driver that exposed the contents of the vga password register to userspace. It would present the entire register instead of interpreting it. The drm implementation chose to mask of the lower bit, without explaining why. This breaks the existing userspace, which is looking for 0xa8 in the lower byte. Change our implementation to expose the entire register.
