Subject: USB: serial: usb_wwan: remove redundant assignment to variable i
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=4ac56b1f1ef8139dbfc5dab918aa235e8344ec4e;p=uclinux-h8%2Flinux.git

USB: serial: usb_wwan: remove redundant assignment to variable i

Variable i is being assigned a value that is never read, it is being
re-assigned two statements later in a for-loop. The assignment is
redundant and can be removed.

Cleans up clang scan build warning:
drivers/usb/serial/usb_wwan.c:151:2: warning: Value stored to 'i'
is never read [deadcode.DeadStores]
