Staging: rtl8712/rtl8192u: move USB device ID within staging drivers.

It seems the USB device ID 0bda:8192 is wrongly assigned to the
RTL8192SU chip and not to the RTL8191SU chip in the USB database.
So this patch moves this device ID from the rtl8192u staging
driver to the rtl8712 staging driver.

This patch was tested with a Radicom WIFIHU embedded wireless
module with a RTL8191SU chip and the USB device ID 0bda:8192.
Without the patch the rtl8192u driver claims this device, but
it does not work. With the patch the rtl8712 driver services
this device and it works.

Staging: bcm: fix possible memory leak of 'pstAddIndication' in CmHost.c and removes a whitespace

Memory is being allocated by kmalloc and stored in
variable pstAddIndication.  However, this memory is
not being freed in all cases. Therefore, this patch
frees it on several exit paths. This patch also
removes a whitespace.

staging: ozwpan: remove debug allocator

The kernel already has a debug allocator, no need to have one unique to
a single driver.  So delete it, replace with kfree, kmalloc, and, in a
few places that need it, kzalloc().

Staging:android: Change type for binder_debug_no_lock switch to bool

GCC warns that module_param_named() indirectly returns a bool type value
which is different from 'int' type binder_debug_no_lock declared. Change
it to bool because it is a internal switch for debugging.

staging: android/lowmemorykiller: Don't unregister notifier from atomic context

The lowmemorykiller registers an atomic notifier for notfication of when
the task is freed.  From this atomic notifier callback, it removes the
atomic notifier via task_free_unregister().  This is incorrect because
atomic_notifier_chain_unregister() calls syncronize_rcu(), which can
sleep, which shouldn't be done from an atomic notifier.

Fix this by registering the notifier during init, and only unregister it
if the lowmemorykiller is unloaded.

staging:iio: Fix compile error without CONFIG_DEBUG_FS

commit e553f182d ("staging: iio: core: Introduce debugfs support, add support
for direct register access") added a '#if defined(CONFIG_DEBUG_FS)' around
iio_read_channel_ext_info and iio_write_channel_ext_info causing the following
compile error if CONFIG_DEBUG_FS is not defined.

	drivers/staging/iio/industrialio-core.c:621:11: error: 'iio_read_channel_ext_info' undeclared (first use in this function)
	drivers/staging/iio/industrialio-core.c:623:11: error: 'iio_write_channel_ext_info' undeclared (first use in this function)

This patch fixes the issue by moving the functions out of the '#if
defined(CONFIG_DEBUG_FS)' section again.

zcache cannot currently be loaded as a module.  However
the Kconfig allows it to be built as a module; something that
the user probably does not intend since the module is not

staging: zsmalloc: add ZS_MAX_PAGES_PER_ZSPAGE

This patch moves where max_zspage_order is declared and
changes its meaning.  "Order" typically implies 2^order
of something; however, it is currently being used as the
"maximum number of single pages in a zspage".  To add clarity,
ZS_MAX_ZSPAGE_ORDER is now used to calculate ZS_MAX_PAGES_PER_ZSPAGE,
which is 2^ZS_MAX_ZSPAGE_ORDER and is the upper bound on the number
of pages in a zspage.
