[PATCH 5.6 160/166] mtd: lpddr: Fix a double free in probe()
From: Greg Kroah-Hartman
Date: Wed Apr 22 2020 - 06:27:53 EST
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 4da0ea71ea934af18db4c63396ba2af1a679ef02 upstream.
This function is only called from lpddr_probe(). We free "lpddr" both
here and in the caller, so it's a double free. The best place to free
"lpddr" is in lpddr_probe() so let's delete this one.
Fixes: 8dc004395d5e ("[MTD] LPDDR qinfo probing.")
