| Subject: mtd: mtdoops: skip reading initially bad blocks |
| |
| From: Roman Tereshonkov <roman.tereshonkov@nokia.com> |
| |
| commit 3538c56329936c78f7d356889908790006d0124c upstream. |
| |
| Use block_isbad to check and skip the bad blocks reading. |
| This will allow to get rid of the read errors if bad blocks |
| are present initially. |
