Subject[PATCH] usb: host: u132-hcd: remove redundant variable num_ports
Date
From: Colin Ian King <colin.king@canonical.com>

Variable num_ports is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'num_ports' set but not used [-Wunused-but-set-variable]

Signed-off-by: Colin Ian King <colin.king@canonical.com>
