[PATCH] Remove of_node_put from drivers/video/fbdev/offb.c

From: Aryabhatta Dey
Date: Thu May 02 2024 - 16:01:26 EST


Add __free(device_node) to the declaration of the pointer pointing to the pci
parent.
This change replaces the manual clean up done by of_node_put() with scope based
memory management.
