The issue arises because the `deflink` structure\nis not properly initialized with the `sta` context. This patch ensures that the\n`deflink` structure is correctly linked to the `sta` context, preventing the\nnull pointer dereference.\n\n BUG: kernel NULL pointer dereference, address: 0000000000000400\n #PF: supervisor read access in kernel mode\n #PF: error_code(0x0000) - not-present page\n PGD 0 P4D 0\n Oops: Oops: 0000 [#1] PREEMPT SMP NOPTI\n CPU: 0 UID: 0 PID: 470 Comm: mt76-usb-rx phy Not tainted 6.12.13-gentoo-dist #1\n Hardware name: /AMD HUDSON-M1, BIOS 4.6.4 11/15/2011\n RIP: 0010:mt792x_rx_get_wcid+0x48/0x140 [mt792x_lib]\n RSP: 0018:ffffa147c055fd98 EFLAGS: 00010202\n RAX: 0000000000000000 RBX: ffff8e9ecb652000 RCX: 0000000000000000\n RDX: 0000000000000000 RSI: 0000000000000001 RDI: ffff8e9ecb652000\n RBP: 0000000000000685 R08: ffff8e9ec6570000 R09: 0000000000000000\n R10: ffff8e9ecd2ca000 R11: ffff8e9f22a217c0 R12: 0000000038010119\n R13: 0000000080843801 R14: ffff8e9ec6570000 R15: ffff8e9ecb652000\n FS: 0000000000000000(0000) GS:ffff8e9f22a00000(0000) knlGS:0000000000000000\n CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n CR2: 0000000000000400 CR3: 000000000d2ea000 CR4: 00000000000006f0\n Call Trace:\n \n ?
