CVE-2024-26854: In the Linux kernel, the following vulnerability has been resolved:  ice: fix uninitialized dplls mutex usage  The pf->dplls.lock mutex is initialized too late, after its first use. Move it to the top of ice_dpll_init. Note that the "err_exit" error path destroys the mutex. And the mutex is the last thing destroyed in ice_dpll_deinit. This fixes the following warning with CONFIG_DEBUG_MUTEXES:   ice 0000:10:00.0: The DDP package was successfully loaded: ICE OS Default Package version 1.3.36.0  ice 0000:10:00.0: 252.048 Gb/s available PCIe bandwidth (16.0 GT/s PCIe x16 link)  ice 0000:10:00.0: PTP init successful  ------------[ cut here ]------------  DEBUG_LOCKS_WARN_ON(lock->magic != lock)  WARNING: CPU: 0 PID: 410 at kernel/locking/mutex.c:587 __mutex_lock+0x773/0xd40  Modules linked in: crct10dif_pclmul crc32_pclmul crc32c_intel polyval_clmulni polyval_generic ice(+) nvme nvme_c>  CPU: 0 PID: 410 Comm: kworker/0:4 Not tainted 6.8.0-rc5+ #3  Hardware name: HPE ProLiant DL110 Gen10 Plus/ProLiant DL110 Gen10 Plus, BIOS U56 10/19/2023  Workqueue: events work_for_cpu_fn  RIP: 0010:__mutex_lock+0x773/0xd40  Code: c0 0f 84 1d f9 ff ff 44 8b 35 0d 9c 69 01 45 85 f6 0f 85 0d f9 ff ff 48 c7 c6 12 a2 a9 85 48 c7 c7 12 f1 a>  RSP: 0018:ff7eb1a3417a7ae0 EFLAGS: 00010286  RAX: 0000000000000000 RBX: 0000000000000002 RCX: 0000000000000000  RDX: 0000000000000002 RSI: ffffffff85ac2bff RDI: 00000000ffffffff  RBP: ff7eb1a3417a7b80 R08: 0000000000000000 R09: 00000000ffffbfff  R10: ff7eb1a3417a7978 R11: ff32b80f7fd2e568 R12: 0000000000000000  R13: 0000000000000000 R14: 0000000000000000 R15: ff32b7f02c50e0d8  FS:  0000000000000000(0000) GS:ff32b80efe800000(0000) knlGS:0000000000000000  CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033  CR2: 000055b5852cc000 CR3: 000000003c43a004 CR4: 0000000000771ef0  DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000  DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400  PKRU: 55555554  Call Trace:   <TASK>   ? __warn+0x84/0x170   ? __mutex_lock+0x773/0xd40   ? report_bug+0x1c7/0x1d0   ? prb_read_valid+0x1b/0x30   ? handle_bug+0x42/0x70   ? exc_invalid_op+0x18/0x70   ? asm_exc_invalid_op+0x1a/0x20   ? __mutex_lock+0x773/0xd40   ? rcu_is_watching+0x11/0x50   ? __kmalloc_node_track_caller+0x346/0x490   ? ice_dpll_lock_status_get+0x28/0x50 [ice]   ? __pfx_ice_dpll_lock_status_get+0x10/0x10 [ice]   ? ice_dpll_lock_status_get+0x28/0x50 [ice]   ice_dpll_lock_status_get+0x28/0x50 [ice]   dpll_device_get_one+0x14f/0x2e0   dpll_device_event_send+0x7d/0x150   dpll_device_register+0x124/0x180   ice_dpll_init_dpll+0x7b/0xd0 [ice]   ice_dpll_init+0x224/0xa40 [ice]   ? _dev_info+0x70/0x90   ice_load+0x468/0x690 [ice]   ice_probe+0x75b/0xa10 [ice]   ? _raw_spin_unlock_irqrestore+0x4f/0x80   ? process_one_work+0x1a3/0x500   local_pci_probe+0x47/0xa0   work_for_cpu_fn+0x17/0x30   process_one_work+0x20d/0x500   worker_thread+0x1df/0x3e0   ? __pfx_worker_thread+0x10/0x10   kthread+0x103/0x140   ? __pfx_kthread+0x10/0x10   ret_from_fork+0x31/0x50   ? __pfx_kthread+0x10/0x10   ret_from_fork_asm+0x1b/0x30   </TASK>  irq event stamp: 125197  hardirqs last  enabled at (125197): [<ffffffff8416409d>] finish_task_switch.isra.0+0x12d/0x3d0  hardirqs last disabled at (125196): [<ffffffff85134044>] __schedule+0xea4/0x19f0  softirqs last  enabled at (105334): [<ffffffff84e1e65a>] napi_get_frags_check+0x1a/0x60  softirqs last disabled at (105332): [<ffffffff84e1e65a>] napi_get_frags_check+0x1a/0x60  ---[ end trace 0000000000000000 ]---
