staging: wilc1000: remove redundant masking of pkt_offset

The masking update of pkg_offset is redundant as the updated
value is never read and pkg_offset is re-assigned on the next
iteration of the loop.  Clean this up by removing the redundant
assignment.

staging: fieldbus: arcx-anybus: change custom -> mmio regmap

The arcx-anybus's registers are accessed via a memory-mapped
IO region. A regmap associated with this region is created
using custom reg_read() / reg_write() callbacks.

However, an abstraction which creates a memory-mapped IO
region backed regmap already exists: devm_regmap_init_mmio().

Replace the custom regmap with the existing kernel abstraction.
As a pleasant side-effect, sparse warnings now disappear.

staging: kpc2000: added separate show functions for kpc_uio_class device attributes, defined them as read-only and declared them static.

Defined separate simple show functions for each attribute instead of
having a one big one containing a chain of conditionals.

Replaced scnprintf calls with sprintf since all the outputs are short

All of the device attributes are read-only, so used DEVICE_ATTR_RO to
define them.

The definitions are only used to populate the kpc_uio_class_attrs
attribute array, so declared them as static.
