Subject: net: nfs: remove superfluous conversions
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=15eea9a1a8166b4bbab6c02cc426a7cc806ea2ca;p=u-boot.git

net: nfs: remove superfluous conversions

rpc_pkt.u.call.data is an array of uint32_t. There is no need to convert
it to uint32_t *.

memcpy() expects void * as it 1st and 2nd argument. There is no point in
converting pointers to char * before passing them to memcpy().

In ntohl(data[1]) != 0 calling ntohl() is superfluous. If the value is
zero, does not depend on the byte order.
