[PATCH] ARM: amba: Link fb device to its parent

[Loïc Minier]

Some pieces of userspace like debian-installer expect to find the fb0
driver name by readlink-ing /sys/class/graphics/fb0/device/driver but
this was broken with amba-clcd as it sets up fb_info manually and missed
the .device parent pointer.

While this is titled as an ARM patch it's certainly fbdev-specific. I'll
apply it barring any objections from Russell.

BTW this should be "Loïc Minier" not "Lo??c Minier" The original email 
was fine with proper UTF-8 in that regard.  Maybe you should have a look 
at your MUA config so the resulting patch log going into git is not 
dammaged.

My MUA ignores UTF-8 intentionally, but this has no bearing on the status
in my git tree.
