Staging: meilhaus: Correct use of ! and &
ME_IO_SINGLE_TYPE_WRITE_NONBLOCKING and ME_IO_STREAM_CONFIG_WRAPAROUND both
hanve 0 as the rightmost bit, and thus eg
!flags & ME_IO_SINGLE_TYPE_WRITE_NONBLOCKING is always 0.
I assume that !(flags & ME_IO_SINGLE_TYPE_WRITE_NONBLOCKING) and
!(flags & ME_IO_STREAM_CONFIG_WRAPAROUND) were intended.
The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@ expression E; constant C; @@
(
!E & !C
|
- !E & C
+ !(E & C)
)
// </smpl>
