Subject: [PATCH] mtd: fix calculating partition end address

This fixes check for partitions that don't start at beginning of their
|
||
|
|
parents. Missing partition's offset in formula could result in forcing
|
||
|
|
read-only incorrectly.
|
||
|
|
|
||
|
|
Fixes: 6750f61a13a0 ("mtd: improve calculating partition boundaries when checking for alignment")
