However, because the drvdata was already set,\nsub-drivers like cros_ec_typec can still retrieve the stale pointer via the\nplatform device. This leads to a use-after-free when cros_ec_typec attempts\nto access &typec->ec->ec->dev on a device that has already been released.\nMove dev_set_drvdata() to ensure that the pointer is only made available\nonce all initialization steps have succeeded.\n\n sysfs: cannot create duplicate filename '/class/chromeos/cros_ec'\n Call trace:\n  sysfs_do_create_link_sd+0x94/0xdc\n  sysfs_create_link+0x30/0x44\n  device_add_class_symlinks+0x90/0x13c\n  device_add+0xf0/0x50c\n  ec_device_probe+0x150/0x4f0\n  platform_probe+0xa0/0xe0\n ...\n BUG: KASAN: invalid-access in __memcpy+0x44/0x230\n Write at addr f5ffff809e2d33ac by task kworker/u32:5/125\n Pointer tag: [f5], memory tag: [fe]\n Tainted : [W]=WARN, [O]=OOT_MODULE\n Hardware name: Google Navi unprovisioned 0x7FFFFFFF/sku0 board/sku3\n Workqueue: events_unbound deferred_probe_work_func\n Call trace:\n  __memcpy+0x44/0x230\n  cros_ec_check_features+0x60/0xcc [cros_ec_proto]\n  cros_typec_probe+0xe8/0x6e0 [cros_ec_typec]\n  platform_probe+0xa0/0xe0",
