Masami Ichikawa c606850407 PM / sleep: Fix memory leak in pm_vt_switch_unregister(). ... kmemleak reported a memory leak as below. unreferenced object 0xffff880118f14700 (size 32): comm "swapper/0", pid 1, jiffies 4294877401 (age 123.283s) hex dump (first 32 bytes): 00 01 10 00 00 00 ad de 00 02 20 00 00 00 ad de .......... ..... 00 d4 d2 18 01 88 ff ff 01 00 00 00 00 04 00 00 ................ backtrace: [<ffffffff814edb1e>] kmemleak_alloc+0x4e/0xb0 [<ffffffff811889dc>] kmem_cache_alloc_trace+0x1ec/0x260 [<ffffffff810aba66>] pm_vt_switch_required+0x76/0xb0 [<ffffffff812f39f5>] register_framebuffer+0x195/0x320 [<ffffffff8130af18>] efifb_probe+0x718/0x780 [<ffffffff81391495>] platform_drv_probe+0x45/0xb0 [<ffffffff8138f407>] driver_probe_device+0x87/0x3a0 [<ffffffff8138f7f3>] __driver_attach+0x93/0xa0 [<ffffffff8138d413>] bus_for_each_dev+0x63/0xa0 [<ffffffff8138ee5e>] driver_attach+0x1e/0x20 [<ffffffff8138ea40>] bus_add_driver+0x180/0x250 [<ffffffff8138fe74>] driver_register+0x64/0xf0 [<ffffffff813913ba>] __platform_driver_register+0x4a/0x50 [<ffffffff8191e028>] efifb_driver_init+0x12/0x14 [<ffffffff8100214a>] do_one_initcall+0xfa/0x1b0 [<ffffffff818e40e0>] kernel_init_freeable+0x17b/0x201 In pm_vt_switch_required(), "entry" variable is allocated via kmalloc(). So, in pm_vt_switch_unregister(), it needs to call kfree() when object is deleted from list.
