Merge the assignment and return statements to return the value
directly. Done using the following semantic patch by coccinelle.

local idexpression ret;
expression e;
@@
-ret =
+return
e;
-return ret;
Also, remove the variable declaration and some braces
that became useless after the merge.

The driver may sleep under a spinlock.
The function call path is:
update_beacon (acquire the spinlock)
update_BCNTIM
set_tx_beacon_cmd
kzalloc(GFP_KERNEL) --> may sleep
kmemdup(GFP_KERNEL) --> may sleep
To fix it, GFP_KERNEL is replaced with GFP_ATOMIC.
This bug is found by my static analysis tool(DSAC) and checked by my code review.

Devices on MC bus can be deferred because of dependencies on other modules
(such as IOMMU). Those are not the actual errors; as probing is again
done by the kernel at later stages. So this patch avoids the error print
in such case.

Following is the current scenario when the devices are probed:
FSL_MC Bus probe ---> dprc probe ---> dprc devices scan --->
probe devices in DPRC container ---> allocate IRQ's
In case the devices being probed in the DPRC container need the IRQ's;
probing of that device will fail.
In current scenario the devices which need IRQ's such as DPIO gets
deferred because they aren't registered when first time the probing
of these devices is done in the dprc scan.
So they are probed once IRQ's have been allocated.
In case where DPRC probing itself gets deferred, which does in case
IOMMU is enabled; all the devices in DPRC container gets probed before
IRQ's are allocated. This causes devices using IRQ's (such as DPIO)
to fail.
So having IRQ's allocated before any of the devices in the DPRC container
are probed is more legitimate.
After this patch following is the flow of execution:
FSL_MC Bus probe ---> dprc probe ---> dprc devices scan --->
allocate IRQ's ---> probe of devices in DPRC container.

A malicious USB device with crafted descriptors can cause the kernel
to access unallocated memory by setting the bNumInterfaces value too
high in a configuration descriptor. Although the value is adjusted
during parsing, this adjustment is skipped in one of the error return
paths.
This patch prevents the problem by setting bNumInterfaces to 0
initially. The existing code already sets it to the proper value
after parsing is complete.

Commit:
681fbec881de ("lockdep: Use consistent printing primitives")
has moved lockdep away from using printk() for printing.
The commit added usage of pr_cont() which wasn't wrapped in the
userspace headers, causing the following warning for the
liblockdep build:
../../../kernel/locking/lockdep.c:3544:2: warning: implicit declaration of function 'pr_cont' [-Wimplicit-function-declaration]
Adding an empty declaration of 'pr_cont' fixes the problem.
