## Description

In the Linux kernel, the following vulnerability has been resolved:  iio: trigger: sysfs: fix possible memory leak in iio_sysfs_trig_init()  dev_set_name() allocates memory for name, it need be freed when device_add() fails, call put_device() to give up the reference that hold in device_initialize(), so that it can be freed in kobject_cleanup() when the refcount hit to 0.  Fault injection test can trigger this:  unreferenced object 0xffff8e8340a7b4c0 (size 32):   comm "modprobe", pid 243, jiffies 4294678145 (age 48.845s)   hex dump (first 32 bytes):     69 69 6f 5f 73 79 73 66 73 5f 74 72 69 67 67 65  iio_sysfs_trigge     72 00 a7 40 83 8e ff ff 00 86 13 c4 f6 ee ff ff  r..@............   backtrace:     [<0000000074999de8>] __kmem_cache_alloc_node+0x1e9/0x360     [<00000000497fd30b>] __kmalloc_node_track_caller+0x44/0x1a0     [<000000003636c520>] kstrdup+0x2d/0x60     [<0000000032f84da2>] kobject_set_name_vargs+0x1e/0x90     [<0000000092efe493>] dev_set_name+0x4e/0x70
