2010-08-02UBI: do not warn unnecessarilyArtem Bityutskiy2-4/+41
Currently, when UBI attaches an MTD device and cannot reserve all 1% (by default) of PEBs for bad eraseblocks handling, it prints a warning. However, Matthew L. Creech <mlcreech@gmail.com> is not very happy to see this warning, because he did reserve enough of PEB at the beginning, but with time some PEBs became bad. The warning is not necessary in this case. This patch makes UBI print the warning o if this is a new image o of this is used image and the amount of reserved PEBs is only 10% (or less) of the size of the reserved PEB pool.

The OOB handling in the mxc_nand driver is broken for v1 type controllers (i.MX27/31) with 512 byte page size. This perhaps did not show up because ubi does not use OOB. Update the driver to always read/write a whole page even if only OOB is requested. With this patch the driver passes the mtd_oobtest on i.MX27 with 512 byte page size.

Both of_bus_type and of_platform_bus_type are just #define aliases for the platform bus. This patch removes all references to them and switches to the of_register_platform_driver()/of_unregister_platform_driver() API for registering. Subsequent patches will convert each user of of_register_platform_driver() into plain platform_drivers without the of_platform_driver shim. At which point the of_register_platform_driver()/of_unregister_platform_driver() functions can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

2010-06-16UBI: improve delete-compatible volumes handlingBrijesh Singh1-2/+2
When a delete-compatible volume is found, it is first added to the 'corr' list, which contains "corrupted" PEBs which should be erased, and then it is added to the used volumes tree. However, the second step should not be done. This does not cause problems in practice, because we never access delete-compattible volumes, but it is still not the right thing to do.

2010-06-04UBI: improve corrupted flash handlingArtem Bityutskiy1-19/+82
This patch improves the way UBI handles corrupted flash, or flash containing garbage or non-UBI data, which is the same from UBI POW. Namely, we do the following: * if 5% or more PEBs are corrupted, refuse the flash * if less than 5% PEBs are corrupted, do not refuse the flash and format these PEBs * if less than 8 PEBs are corrupted, format them silently, otherwise print a warning message.

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang1-2/+0
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.

The following structure elements duplicate the information in 'struct device.of_node' and so are being eliminated. This patch makes all readers of these elements use device.of_node instead. (struct of_device *)->node (struct dev_archdata *)->prom_node (sparc) (struct dev_archdata *)->of_node (powerpc & microblaze) Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2010-05-18mtd: mtdchar: Do not corrupt backing device of device node inodeKirill A. Shutemov1-8/+87
We cannot modify file->f_mapping->backing_dev_info, because it will corrupt backing device of device node inode, since file->f_mapping is equal to inode->i_mapping (see __dentry_open() in fs/open.c). Let's introduce separate inode for MTD device with appropriate backing device. [dwmw2: Refactor to keep it all entirely within mtdchar.c; use iget_locked()] Signed-off-by: Kirill A.

2010-05-16drivers/mtd: Use kmemdupJulia Lawall1-2/+1
Use kmemdup when some other buffer is immediately copied into the allocated region. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression from,to,size,flag; statement S; @@ - to = \(kmalloc\|kzalloc\)(size,flag); + to = kmemdup(from,size,flag); if (to==NULL || ...) S - memcpy(to, from, size); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
