6.1-stable review patch. If anyone has any objections, please let me know.

From: Thomas Zimmermann tzimmermann@suse.de
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)
