netfilter: nfnetlink_cthelper: Remove 'const' and '&' to avoid warnings
commit b18c5d15e8714336365d9d51782d5b53afa0443c upstream. The related code can be simplified, and also can avoid related warnings (with allmodconfig under parisc): CC [M] net/netfilter/nfnetlink_cthelper.o net/netfilter/nfnetlink_cthelper.c: In function ‘nfnl_cthelper_from_nlattr’: net/netfilter/nfnetlink_cthelper.c:97:9: warning: passing argument 1 o ‘memcpy’ discards ‘const’ qualifier from pointer target type [-Wdiscarded-array-qualifiers] memcpy(&help->data, nla_data(attr), help->helper->data_len); ^ In file included from include/linux/string.h:17:0, from include/uapi/linux/uuid.h:25, from include/linux/uuid.h:23, from include/linux/mod_devicetable.h:12, from ./arch/parisc/include/asm/hardware.h:4, from ./arch/parisc/include/asm/processor.h:15, from ./arch/parisc/include/asm/spinlock.h:6, from ./arch/parisc/include/asm/atomic.h:21, from include/linux/atomic.h:4, from ./arch/parisc/include/asm/bitops.h:12, from include/linux/bitops.h:36, from include/linux/kernel.h:10, from include/linux/list.h:8, from include/linux/module.h:9, from net/netfilter/nfnetlink_cthelper.c:11: ./arch/parisc/include/asm/string.h:8:8: note: expected ‘void *’ but argument is of type ‘const char (*)[]’ void * memcpy(void * dest,const void *src,size_t count); ^ Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@soleta.eu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
