net: fix endian check warning in etherdevice.h
Sparse builds have been warning for a really long time now that etherdevice.h has a conversion that is unsafe. include/linux/etherdevice.h:79:32: warning: restricted __be16 degrades to integer This code change fixes the issue and generates the exact same assembly before/after (checked on x86_64) Fixes: 2c722fe1c821 (etherdevice: Optimize a few is_<foo>_ether_addr functions) Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> CC: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
