Subject: net/smc: remove local variable page in smc_rx_splice()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=48bf5231771c7e3961c8326353b6027b1bed6eb5;p=linux.git

net/smc: remove local variable page in smc_rx_splice()

The page map address is already stored in the RMB descriptor.
There is no need to derive it from the cpu_addr value.
