Subject: USB: whci-hcd: Delete an unnecessary check before the function call "usb_put_hcd"
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=28ed20755897b3726f07a0418c3d2fe17b3e5c86;p=openwrt%2Fstaging%2Fblogic.git

USB: whci-hcd: Delete an unnecessary check before the function call "usb_put_hcd"

The usb_put_hcd() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
