[PATCH 1/2] usb: typec: tipd: Fix dereferencing freeing memory in tps6598x_apply_patch()
From: Harshit Mogalapalli
Date: Wed Jul 24 2024 - 12:24:25 EST
release_firmware() already frees fw, fix this my moving release_firmware
after the dereference.
Fixes: 916b8e5fa73d ("usb: typec: tipd: add error log to provide firmware name and size")
