Subject: [PATCH v2] staging: silicom: Remove unused pointer in
 bypass_init_module()

Pointer 'pbpctl_dev_c' in function bypass_init_module() is unused. Thus remove
it. With the last variable declaration gone, there is no more need for an own
block. Remove it and adapt the indenting accordingly.

Signed-off-by: Christian Engelmayer <cengelma@....at>

v2: Added changes requested by Dan Carpenter:

    Dan pointed out that with the declaration gone, the indent block shall be
    removed. This was intentionally left out in v1 in order to keep the
    changeset more readable. However, according to the input, also with the
    additional indenting change this still qualifies for one logical change.

Compile tested and applies against v3.15-rc2 as well as branch staging-next
of tree git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
