H A D | i2c-s3c2410.c | diff da6801e38b7fba28fbdc0ceae6681d5a261a42a6 Thu Oct 30 15:55:47 CET 2008 Julia Lawall <julia@diku.dk> i2c-s3c2410: Correct use of ! and &
In commit e6bafba5b4765a5a252f1b8d31cbf6d2459da337, 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>
