78110bb8dc staging: Remove unnecessary OOM messages
alloc failures already get standardized OOM
messages and a dump_stack.

For the affected mallocs around these OOM messages:

Converted kzallocs with multiplies to kcalloc.
Converted kmallocs with multiplies to kmalloc_array.
Converted a kmalloc/strlen/strncpy to kstrdup.
Moved a spin_lock below a removed OOM message and
removed a now unnecessary spin_unlock.
Neatened alignment and whitespace.

955e7da82d staging: ced1401: fix GFP_KERNEL in spinlock context
Allowi() calls usb_submit_urb(pdx->pUrbCharIn, bInCallback ? GFP_ATOMIC : GFP_KERNEL)
under spin_lock_irqsave(&pdx->charInLock, flags). That means it should use GFP_ATOMIC anyway.
As soon as it is the only usage of bInCallback argument, the patch removes it at all.

Found by Linux Driver Verification project (linuxtesting.org).

ff549e4772 staging: ced1401: remove an obvious commit about the minor number
in disconnect we assign the device minor number from the interface
pointer to the localvarible minor, and then print it at the end,

this code seems self explanatory so remove the comment of assigning
the minor number to a local variable.

As the driver says that read and writes should not be performed
and instead the user to kernel transactions are performed through
ioctl interface, remove these functions as they are not required

This adds the ced1401 driver to the build system.

Yes, there are a lot of warning messages, but it does compile, so it
should be good to get going.

6ede1edea3 Staging: ced1401: usb1401: fix build errors.
This fixes up the usb1401.c file to remove the usage of err() (which is
gone), and the two-argument kmap_atomic() call, and the compat_ioctl
pointer warning.

The code now builds properly, there are lots of warnings still, but it's
a start.

2eae6bdc12 Staging: add ced1401 USB driver
This was imported from the
http://pub.ist.ac.at/~schloegl/src/ced1401/.git git repo at the request
of Alois.  The driver originally came from Cambridge Electronic Design
Ltd and was authored by Greg P Smith and others, but Alois did the
maintance work to get it into a semi-building state and pushed to get it
into the main kernel tree here.
