Subject: USB: serial: keyspan_pda: remove unused variable
X-Git-Tag: v4.4.251~7
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=460ebb463c9a5c015bffa4233dac0cde57d34507;p=thirdparty%2Fkernel%2Fstable.git

USB: serial: keyspan_pda: remove unused variable

Remove an unused variable which was mistakingly left by commit
37faf5061541 ("USB: serial: keyspan_pda: fix write-wakeup
use-after-free") and only removed by a later change.

This is needed to suppress a W=1 warning about the unused variable in
the stable trees that the build bots triggers.
