Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

drivers/isdn: delete double assignment Delete successive assignments to the same location. In the first case, the hscx array has two elements, so change the assignment to initialize the second one. In the second case, the two assignments are simply identical. Furthermore, neither is necessary, because the effect of the assignment is only visible in the next line, in the assignment in the if test. The patch inlines the right hand side value in the latter assignment and pulls that assignment out of the if test. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression i; @@ *i = ...; i = ...; // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.
