pps_register_cdev when register device fail\n\nSimilar to previous commit 2a934fdb01db (\"media: v4l2-dev: fix error\nhandling in __video_register_device()\"), the release hook should be set\nbefore device_register(). Otherwise, when device_register() return error\nand put_device() try to callback the release function, the below warning\nmay happen.\n\n ------------[ cut here ]------------\n WARNING: CPU: 1 PID: 4760 at drivers/base/core.c:2567 device_release+0x1bd/0x240 drivers/base/core.c:2567\n Modules linked in:\n CPU: 1 UID: 0 PID: 4760 Comm: syz.4.914 Not tainted 6.17.0-rc3+ #1 NONE\n RIP: 0010:device_release+0x1bd/0x240 drivers/base/core.c:2567\n Call Trace:\n <TASK>\n kobject_cleanup+0x136/0x410 lib/kobject.c:689\n kobject_release lib/kobject.c:720 [inline]\n kref_put include/linux/kref.h:65 [inline]\n kobject_put+0xe9/0x130 lib/kobject.c:737\n put_device+0x24/0x30 drivers/base/core.c:3797\n pps_register_cdev+0x2da/0x370 drivers/pps/pps.c:402\n pps_register_source+0x2f6/0x480 drivers/pps/kapi.c:108\n pps_tty_open+0x190/0x310 drivers/pps/clients/pps-ldisc.c:57\n tty_ldisc_open+0xa7/0x120 drivers/tty/tty_ldisc.c:432\n tty_set_ldisc+0x333/0x780 drivers/tty/tty_ldisc.c:563\n tiocsetd drivers/tty/tty_io.c:2429 [inline]\n tty_ioctl+0x5d1/0x1700 drivers/tty/tty_io.c:2728\n vfs_ioctl fs/ioctl.c:51 [inline]\n __do_sys_ioctl fs/ioctl.c:598 [inline]\n __se_sys_ioctl fs/ioctl.c:584 [inline]\n __x64_sys_ioctl+0x194/0x210 fs/ioctl.c:584\n do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline]\n do_syscall_64+0x5f/0x2a0 arch/x86/entry/syscall_64.c:94\n entry_SYSCALL_64_after_hwframe+0x76/0x7e\n </TASK>\n\nBefore commit c79a39dc8d06 (\"pps: Fix a use-after-free\"),\npps_register_cdev() call device_create() to create pps->dev, which will\ninit dev->release to device_create_release().
