From 7b844cf445f0a7daa68be0ce71eb2c88d68b0c5d Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Mon, 4 Jan 2021 09:41:37 +0530 Subject: mtd: parsers: afs: Fix freeing the part name memory in failure In the case of failure while parsing the partitions, the iterator should be pre decremented by one before starting to free the memory allocated by kstrdup(). Because in the failure case, kstrdup() will not succeed and thus no memory will be allocated for the current iteration.
