Subject: [PATCH 31/32] usb: host: fhci-sched: Remove unused variable 'td'
Date: Mon,  6 Jul 2020 14:33:40 +0100	[thread overview]
Message-ID: <20200706133341.476881-32-lee.jones@linaro.org> (raw)
In-Reply-To: <20200706133341.476881-1-lee.jones@linaro.org>

'td' has been completely unused since the driver's inception in 2009.

Fixes the following W=1 kernel build warning(s):

 drivers/usb/host/fhci-sched.c: In function ‘fhci_queue_urb’:
 drivers/usb/host/fhci-sched.c:704:13: warning: variable ‘td’ set but not used [-Wunused-but-set-variable]
 704 | struct td *td;
 | ^~
