In case there are no DT idle states defined or cpuidle_register_driver() fails, the copy of the idle driver is leaked: unreferenced object 0xede0dc00 (size 1024): comm "swapper/0", pid 1, jiffies 4294937431 (age 744.510s) hex dump (first 32 bytes): 94 9e 0b c1 00 00 00 00 00 00 00 00 00 00 00 00 ................ 57 46 49 00 00 00 00 00 00 00 00 00 00 00 00 00 WFI............. backtrace: [<c1295f04>] arm_idle_init+0x44/0x1ac [<c0301e6c>] do_one_initcall+0x3c/0x16c [<c1200d70>] kernel_init_freeable+0x110/0x1d0 [<c0cb3624>] kernel_init+0x8/0x114 [<c0307a98>] ret_from_fork+0x14/0x3c So fix this by freeing the unregistered copy in error case.
