During the probe for physmap platform flash devices there are a
number error exit conditions that all do a goto err_out which
then calls physmap_flash_remove().  In that function one of the
cleanup steps is:

#ifdef CONFIG_MTD_CONCAT
	if (info->cmtd != info->mtd[0])
		mtd_concat_destroy(info->cmtd);
#endif

This test will succeed since info->cmtd == NULL and info->mtd[0] is
valid.

Fix this by exiting the remove function when info->cmtd == NULL.

Also, cleanup the #ifdef CONFIG_MTD_PARTITIONS stuff by using
mtd_has_partitions().

Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

This driver seems to be obsolete and broken for a long time.
It depends on CONFIG_IPAQ_HANDHELD that simply doesn't exists
anywhere in kernel. Also, it seems that none of machines it
claims to support have any use of it:
 SA11xx-based iPAQs (h3100/h3600) use sa1100-flash
 iPAQ h5000 uses physmap-flash
 Jornada 720 uses sa1100-flash
 Jornada 560 and iPAQ h1910 are not in mainline

Fix a potential memory leak in mtd_dataflash driver.

The private data that is allocated when registering a DataFlash
device with the MTD subsystem is not released if an error occurs
when add_mtd_partitions() or add_mtd_device() is called.  Fix this
by adding an error path.  The memory is already released during a
remove.

Also, add a dev_set_drvdata(&spi->dev, NULL) before the kfree() so
that the spi device does not reference invalid data.

For this system call user space passes a signed long length parameter,
while the kernel side takes an unsigned long parameter and converts it
later to signed long again.

This has led to bugs in compat wrappers see e.g.  dd90bbd5 "powerpc: Add
compat_sys_truncate".  The s390 compat wrapper for this functions is
broken as well since it also performs zero extension instead of sign
extension for the length parameter.

In addition if hpa comes up with an automated way of generating
compat wrappers it would generate a wrong one here.

So change the length parameter from unsigned long to long.
