driver core: module.c: Use kasprintf
kasprintf combines kmalloc and sprintf, and takes care of the size calculation itself. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression a,flag; expression list args; statement S; @@ a = - \(kmalloc\|kzalloc\)(...,flag) + kasprintf(flag,args) <... when != a if (a == NULL || ...) S ...> - sprintf(a,args); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
