From e980048263ba72dcdbbf45d59e84c02001340f75 Mon Sep 17 00:00:00 2001 From: Muhammad Usama Anjum Date: Fri, 9 Apr 2021 00:57:18 +0500 Subject: spi: orion: set devdata properly as it is being used later If device_get_match_data returns NULL, devdata isn't being updated properly. It is being used later in the function. Both devdata and spi->devdata should be updated to avoid NULL pointer dereference.
