Subject: [PATCH] USB: remove redundant assignment to temp
Date: Tue, 7 Nov 2017 10:27:59 +0000 [thread overview]
Message-ID: <20171107102759.10456-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The variable temp is being set at the end of each loop iteration
but this value is never read, it is either being updated in just
the case 1 block or at the end of the loop. Thus the assignment
is redundant and can be removed. Cleans up clang warning:
drivers/usb/host/ehci-dbg.c:840:4: warning: Value stored to 'temp'
is never read
