Subject: linux-next: net tree build warning

Hi Dave,

Today's linux-next build (x86_64 allmodconfig gcc-4.4.0) produced this
warning:

drivers/net/wan/dscc4.c: In function 'dscc4_rx_skb':
drivers/net/wan/dscc4.c:670: warning: suggest parentheses around comparison in operand of '|'

which actually points out a bug, I think.  It is doing
	(x & (y | z)) != y | z
when it probably means
	(x & (y | z)) != (y | z)

Introduced by commit 5de3fcab91b0e1809eec030355d15801daf25083 ("WAN: bit
and/or confusion").
