However it is a fact that many OEMs hardcoded the configurations needed by CSC3551 into their proprietary software for various 2022 and later laptop models, and this makes the Linux installations on these models cannot make any speaker sound. Meanwhile, at this point of time, we see no hope that these OEMs would ever fix this problem via a BIOS update. So to fix this bothering problem it might be worthwhile to add some model-specific fixups to apply some proper configurations to the cs35l41. To address the above problem, a configuration fixup function apply_cs35l41_fixup_cfg that would be called in cs35l41_no_acpi_dsd, along with a fixup table cs35l41_fixup_cfgtbl which is a array of fixup entry struct cs35l41_fixup_cfg are introduced. Each fixup entry records the ACPI _SUB(vender and device ID) to be matched, and a configuration to be applied to each of the cs35l41 device in CSC3551. More specifically for the design of this fixup mechanism, the maximum number of cs35l41 configurations inside a fixup entry is defined as a macro CS35L41_FIXUP_CFG_MAX_DEVICES, and the actual number of cs35l41 devices in a CSC3551 system is recorded in the num_device field in the fixup entry. The apply_cs35l41_fixup_cfg function is responsible for finding and applying a fixup for a specific model according to the model's ACPI _SUB. If no valid fixup can be applied, the fixup function fails and returns to the normal cs35l41_no_acpi_dsd execution flow. This patch now contains only several fixups for three Lenovo laptop models, namely 16IAH7, 16IAX7, and 16ARHA7 and this fixup mechanism has been verified to work on 16IAH7. As far as is known, several other laptop models from ASUS and HP also suffer from this no valid _DSD problem and could have it addressed with this fixup mechanism when proper fixup entries are inserted.
