This was not detected during regular testing\nwithout driver_async_probe.\n\nConvert the SoC code to platform driver and instantiate a platform device\nin its current device_initcall() to probe the platform driver. Rework\n.soc_revision callback to always return valid error code and return SoC\nrevision via parameter. This way, if anything in the .soc_revision callback\nreturn -EPROBE_DEFER, it gets propagated to .probe and the .probe will get\nretried later.\n\n\"\n------------[ cut here ]------------\nWARNING: CPU: 1 PID: 1 at drivers/soc/imx/soc-imx8m.c:115 imx8mm_soc_revision+0xdc/0x180\nCPU: 1 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.11.0-next-20240924-00002-g2062bb554dea #603\nHardware name: DH electronics i.MX8M Plus DHCOM Premium Developer Kit (3) (DT)\npstate: 20000005 (nzCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--)\npc : imx8mm_soc_revision+0xdc/0x180\nlr : imx8mm_soc_revision+0xd0/0x180\nsp : ffff8000821fbcc0\nx29: ffff8000821fbce0 x28: 0000000000000000 x27: ffff800081810120\nx26: ffff8000818a9970 x25: 0000000000000006 x24: 0000000000824311\nx23: ffff8000817f42c8 x22: ffff0000df8be210 x21: fffffffffffffdfb\nx20: ffff800082780000 x19: 0000000000000001 x18: ffffffffffffffff\nx17: ffff800081fff418 x16: ffff8000823e1000 x15: ffff0000c03b65e8\nx14: ffff0000c00051b0 x13: ffff800082790000 x12: 0000000000000801\nx11: ffff80008278ffff x10: ffff80008209d3a6 x9 : ffff80008062e95c\nx8 : ffff8000821fb9a0 x7 : 0000000000000000 x6 : 00000000000080e3\nx5 : ffff0000df8c03d8 x4 : 0000000000000000 x3 : 0000000000000000\nx2 : 0000000000000000 x1 : fffffffffffffdfb x0 : fffffffffffffdfb\nCall trace:\n imx8mm_soc_revision+0xdc/0x180\n imx8_soc_init+0xb0/0x1e0\n do_one_initcall+0x94/0x1a8\n kernel_init_freeable+0x240/0x2a8\n kernel_init+0x28/0x140\n ret_from_fork+0x10/0x20\n---[ end trace 0000000000000000 ]---\nSoC: i.MX8MP revision 1.1\n\"\n\ud83d\udccf Published: 2025-01-08T17:52:03.420Z\n\ud83d\udccf Modified: 2025-01-08T17:52:03.420Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/e497edb8f31ec2c2b6f4ce930e175aa2da8be334\n2. https://git.kernel.org/stable/c/ea2ff66feb5f9b183f9e2f9d06c21340bd88de12\n3. https://git.kernel.org/stable/c/2129f6faa5dfe8c6b87aad11720bf75edd77d3e4\n4. https://git.kernel.org/stable/c/997a3c04d7fa3d1d385c14691350d096fada648c\n5. https://git.kernel.org/stable/c/9cc832d37799dbea950c4c8a34721b02b8b5a8ff", "creation_timestamp": "2025-01-08T18:18:50.000000Z"}
