Bluetooth: Add missing kmalloc NULL tests to Marvell driver

Author: Julia Lawall <julia@diku.dk> Check that the result of kmalloc is not NULL before dereferencing it. The patch also replaces kmalloc + memset by kzalloc. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression *x; identifier f; constant char *C; @@ x = \(kmalloc\|kcalloc\|kzalloc\)(…); … when != x == NULL …

net/rds: Use AF_INET for sin_family field

Author: Julia Lawall <julia@diku.dk> Elsewhere the sin_family field holds a value with a name of the form AF_…, so it seems reasonable to do so here as well. Also the values of PF_INET and AF_INET are the same. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ struct sockaddr_in sip; @@ …

ARM: 5635/1: Use DIV_ROUND_CLOSEST

Author: Julia Lawall <julia@diku.dk> The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d but is perhaps more readable.

drivers/net/wireless/iwlwifi: introduce missing kfree

Author: Julia Lawall <julia@diku.dk> Move orthogonal error handling code up before a kzalloc, so that it doesn’t have to free the allocated data.
