Julia Lawall da6801e38b i2c-s3c2410: Correct use of ! and &
In commit e6bafba5b4, a bug was fixed that
involved converting !x & y to !(x & y).  The code below shows the same
pattern, and thus should perhaps be fixed in the same way.  In particular,
the result of !readl(i2c->regs + S3C2410_IICCON) & S3C2410_IICCON_IRQEN is
always 0.

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>
