* [JFFS2] Fix cleanup in case of GC-Task not startedThomas Gleixner2005-05-23
| | | | | | | Do not call wait_for_completion, when the gc task is not there. Prevent an oops when the gc thread was not started. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* [MTD] CFI-0002 - Improve error checkingEric W. Biedermann2005-05-23
| | | | | | | Check for errors besides infinite loops when writing and erasing. Signed-off-by: Eric W. Biederman <ebiederman@lnxi.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* [MTD] CFI flash locking reorg for XIPNicolas Pitre2005-05-23
| | | | | | | | | | | This reworks the XIP locking to make sure no lock primitive is ever called from XIP disabled paths even if in theory they should not cause any reschedule. Relying on the current spinlock implementation is rather fragile and not especially clean from an abstraction pov. The recent RT work makes it even more obvious.

* [MTD] ixp2000: Remove port setting codeLennert Buytenhek2005-05-23
| | | | | | | | | | | | | | Setting the slowport to 8-bit mode is something that ought to be done in the IXP2000 generic code, not in the MTD map driver. See the description for ARM patch 2493/1 for an explanation. http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=2493/1 Now that 2493/1 has been accepted and will be upstream soon, this doesn't need to be done in the map driver anymore.
