dm delay: fix a possible deadlock due to shared workqueue

The dm-delay target uses a shared workqueue for multiple instances.  This
can cause deadlock if two or more dm-delay targets are stacked on the top
of each other.

This patch changes dm-delay to use a per-instance workqueue.

gpio: davinci: fix check for unbanked gpio

This patch fixes a check for offset in gpio_to_irq_unbanked()
and also assigns gpio_irq, gpio_unbanked of chips[0] to
appropriate values which is used in gpio_to_irq_unbanked()
function.

Without this patch, unbanked IRQ handling is broken.

ARM: davinci: fix number of resources passed to davinci_gpio_register()

The davinci_gpio_register() function expects the number of
resources as the second parameter, but sizeof() resources
was passed to it due to which it was causing unexpected
behaviour. This patch fixes the same by passing the
ARRAY_SIZE() of resources.

ARC: Add guard macro to uapi/asm/unistd.h

Chen originally proposed this as "right thing to do" however I
actually ran into this when building perf tools. Some of the utils
include unistd.h as well as linux/unistd.h. Since -I includes kernel
headers too, we end up including the ARC unistd.h twice, leading to
redefinition nwarnings.

regmap: use IS_ERR() to check clk_get() results

clk_get() returns an error pointer, or a valid token to pass back to the
clock API. Hence, the result must be checked with IS_ERR(), not by
comparison against NULL.

regulator: core: Check for DT every time we check full constraints

Eliminate the gap between DT becoming available and this being used to say
we have full constraints by checking directly for DT every time we check
