Subject: fbdev/nvidiafb: Reorder backlight and framebuffer init/cleanup
Git-commit: 476a841f35ac47adac2f4c699f3176de86b170b3
Patch-mainline: v6.6-rc1
References: jsc#PED-3527 jsc#PED-5475 jsc#PED-6068 jsc#PED-6070 jsc#PED-6116 jsc#PED-6120 jsc#PED-5065 jsc#PED-5477 jsc#PED-5511 jsc#PED-6041 jsc#PED-6069 jsc#PED-6071
The driver's backlight code requires the framebuffer to be
registered. Therefore reorder the init and cleanup calls for
both data structures.
