Subject: USB: serial: Remove unused s_priv variable
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=996a776544cc8a71653ffa95a89c317f33d2cb4a;p=deliverable%2Flinux.git

USB: serial: Remove unused s_priv variable

s_priv was set but never used in keyspan_open() and keyspan_close(),
remove it.

This also makes the serial variable in keyspan_open() unused since
it's only use was to set s_priv, so it is also removed.
