mtd: physmap: fix NULL pointer dereference in error path

2009-03-10T22:55:11+00:00

commit e480814f138cd5d78a8efe397756ba6b6518fdb6 ("[MTD] [MAPS] physmap:
fix wrong free and del_mtd_{partition,device}") introduces a NULL pointer
dereference in physmap_flash_remove when called from the error path in
physmap_flash_probe (if map_probe failed).

Call del_mtd_{partition,device} only if info->cmtd was not NULL.

[MTD] [MAPS] physmap: fix wrong free and del_mtd_{partition,device}

2009-02-14T08:06:20+00:00

commit 176bf2e0f10ecf1d20a97db3bd5bb2e6ba0b5668 ("physmap: fix leak of
memory returned by parse_mtd_partitions") deals with a memory leak and
frees the pointer array of mtd_partition after the call to
add_mtd_partitions().  the problem is that mtd_table[x]->name still points
to the freed memory.

Aldo physmap_flash_remove() should call del_mtd_partitions() or
del_mtd_device() only once.

[MTD] LPDDR extended physmap driver to support LPDDR flash

2009-01-05T12:57:28+00:00

Physmap is a generic map driver for different platforms and flash types.
We added support of LPDDR to physmap.
All changes here are related to introduction of new pfow_base parameter.
This parameter is valid in case of LPDDR chips only.

[MTD] physmap: fix leak of memory returned by parse_mtd_partitions

2008-12-10T16:10:27+00:00

The mtd partition parser returns an allocated pointer array of
mtd_partition.  The caller must free it.  The array is used only for
add_mtd_partitions(), so free it just after the call.

[MTD] physmap: make physmap compat explicit

2008-12-10T16:10:05+00:00

The current method for always showing physmap compat address, size, and
width is a bit confusing.  If length is set to 0, then the address and
width are still shown but silently unused.  The physmap code itself
already has logic which sets compat based on length, so just pull that out
and into the Kconfig to make everything clear.

[MTD] physmap: fix memory leak on physmap_flash_remove by using devres

2008-11-26T10:26:29+00:00

physmap_flash_remove releases only last memory region.  This causes
memory leak if multiple resources were provided.

This patch fixes this leakage by using devm_ functions.

[MTD] physmap: resume already suspended chips on failure to suspend

2008-07-25T13:53:26+00:00

A nice side effect of this patch is that the return value of
physmap_flash_suspend in the error path is the value of the first failing
suspend callback and not the bitwise OR of all of them.

MTD/JFFS2: remove CVS keywords

2008-06-04T16:50:17+00:00

Once upon a time, the MTD repository was using CVS.

This patch therefore removes all usages of the no longer updated CVS
keywords from the MTD code.

This also includes code that printed them to the user.
