Thanks, just pushed the following out:
WAN: dscc4: Fix warning pointing out a bug.
Noticed by Stephen Rothwell:
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").
