parentlists: add "const" qualifier to first arg of list_splice() operations (diff)
drivers/misc: elide a non-zero test on a result that is never 0
The function thermal_cooling_device_register always returns either a valid pointer or a value made with ERR_PTR, so a test for non-zero on the result will always succeed. The problem was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) //<smpl> @a@ expression E, E1; statement S,S1; position p; @@ E = thermal_cooling_device_register(...) ... when != E = E1 if@p (E) S else S1 @n@ position a.p; expression E,E1; statement S,S1; @@ E = NULL ... when != E = E1 if@p (E) S else S1 @depends on !n@ expression E; statement S,S1; position a.p; @@ * if@p (E) S else S1 //</smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Thomas Sujith <sujith.thomas@intel.com> Cc: Len Brown <len.brown@intel.com> Cc: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
