fbdev/ep93xx-fb: Do not assign to struct fb_info.dev
commit f90a0e5265b60cdd3c77990e8105f79aa2fac994 upstream.
Do not assing the Linux device to struct fb_info.dev. The call to
register_framebuffer() initializes the field to the fbdev device.
Drivers should not override its value.
Fixes a bug where the driver incorrectly decreases the hardware
device's reference counter and leaks the fbdev device.
v2:
* add Fixes tag (Dan)
