Christophe JAILLET 9e40f2c513 drm/nouveau: Fix a potential theorical leak in nouveau_get_backlight_name() ... [ Upstream commit ab244be47a8f111bc82496a8a20c907236e37f95 ] If successful ida_simple_get() calls are not undone when needed, some additional memory may be allocated and wasted. Here, an ID between 0 and MAX_INT is required. If this ID is >=100, it is not taken into account and is wasted. It should be released. Instead of calling ida_simple_remove(), take advantage of the 'max' parameter to require the ID not to be too big. Should it be too big, it is not allocated and don't need to be freed. While at it, use ida_alloc_xxx()/ida_free() instead to ida_simple_get()/ida_simple_remove(). The latter is deprecated and more verbose.
