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) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Fixes: 88017bda96a5 ("ep93xx video driver") Cc: <stable@vger.kernel.org> # v2.6.32+ Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20230613110953.24176-15-tzimmermann@suse.de Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
