Subject: [PATCH] staging: silicom: Remove needless calls of
 get_status_port_fn()

Remove a needless pointer initialisation and call to get_status_port_fn()
in functions remove_bypass_tpl_auto() and set_tpl_fn(). Variable
'pbpctl_dev_b' is set correctly later in the function before first use.

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

Compile tested and applies against v3.15-rc2 as well as branch staging-next
