drm/amdgpu: Replace one-elements array with flex-array members

2022-11-15T18:35:16+00:00

One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in structs ATOM_I2C_VOLTAGE_OBJECT_V3, ATOM_ASIC_INTERNAL_SS_INFO_V2, ATOM_ASIC_INTERNAL_SS_INFO_V3, and refactor the rest of the code accordingly. Important to mention is that doing a build before/after this patch results in no functional binary output differences. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1].

drm/amdgpu: Replace one-element array with flex-array member

2022-11-10T20:30:02+00:00

One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in structs _ATOM_CONNECTOR_DEVICE_TAG_RECORD, _ATOM_OBJECT_GPIO_CNTL_RECORD, _ATOM_BRACKET_LAYOUT_RECORD, _ATOM_BRACKET_LAYOUT_RECORD, _ATOM_LEAKAGE_VOLTAGE_OBJECT_V3, _ATOM_FUSION_SYSTEM_INFO_V3, _ATOM_I2C_DATA_RECORD, _ATOM_I2C_DEVICE_SETUP_INFO, _ATOM_ASIC_MVDD_INFO and refactor the rest of the code accordingly. While at it, removed a redundant casting. Important to mention is that doing a build before/after this patch results in no binary output differences. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1].
