This leads to a general protection fault when\naccessing a near-NULL address.\n\nThe root cause is that vidtv_mux_pid_ctx_init() does not check the\nreturn value of vidtv_mux_create_pid_ctx_once() for PMT section PIDs.\nIf the allocation fails, the PID context is never created, but init\nreturns success. The subsequent vidtv_mux_push_si() call then gets\nNULL from vidtv_mux_get_pid_ctx() and crashes.\n\nFix both the root cause (add error check in vidtv_mux_pid_ctx_init\nfor PMT PIDs) and add defensive NULL checks in vidtv_mux_push_si for\nall vidtv_mux_get_pid_ctx() calls.\n\n[1]\nOops: general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] SMP KASAN PTI\nKASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]\nWorkqueue: events vidtv_mux_tick\nRIP: 0010:vidtv_psi_ts_psi_write_into+0x54a/0xbc0 drivers/media/test-drivers/vidtv/vidtv_psi.c:197\nCall Trace:\n \u003cTASK\u003e\n vidtv_psi_table_header_write_into drivers/media/test-drivers/vidtv/vidtv_psi.c:799 [inline]\n vidtv_psi_pmt_write_into+0x3b2/0xa70 drivers/media/test-drivers/vidtv/vidtv_psi.c:1231\n vidtv_mux_push_si+0x932/0xe80 drivers/media/test-drivers/vidtv/vidtv_mux.c:196\n vidtv_mux_tick+0xe9b/0x1480 drivers/media/test-drivers/vidtv/vidtv_mux.c:408",
