Pull UBI/UBIFS updates from Miquel Raynal:
"This pull request contains mostly fixes for UBI and UBIFS:
UBI:
- Fixes for memory leaks in error paths
- Fix for an logic error in a fastmap selfcheck
UBIFS:
- Fix for FS_IOC_SETFLAGS related to fscrypt flag
- Support for FS_ENCRYPT_FL
- Fix for a dead lock in bulk-read mode"
Sent on behalf of Richard Weinberger who is traveling.
