Matt DeVillier c0998983d0 ec/google/chromeec: Fix uninitialized buffer in cbi_get_uint32() ... Commit e59c5abd13 ("ec/google/chromeec: Add EC_GOOGLE_CHROMEEC_FW_CONFIG_FROM_UFSC") refactored cbi_get_uint32() to write directly to the caller's buffer instead of using a local variable. This caused uninitialized memory (containing garbage addresses) to be passed to the EC as the return buffer during CBI reads. In the case of google/zork, the call to google_chromeec_cbi_get_board_version() returned garbage data (e.g., 0xae6ccd05 vs 0x5) which caused incorrect code paths to be taken: - variant_override_gpio_table() selected wrong GPIO tables based on invalid board version comparisons - variant_touchscreen_update() skipped touchscreen GPIO configuration because variant_uses_v3_6_schematics() returned true for garbage values - variant_uses_codec_gpi() returned wrong value, preventing headphone jack interrupt setup These misconfigurations caused input devices (touchpad, touchscreen, trackpoint) to be non-functional, despite being detected by the OS. The fix restores the original behavior by using a local variable initialized to 0, ensuring a clean buffer is always passed to the EC. TEST=build/boot google/zork, verify board version is read correctly, all input devices functional under Linux/Windows.
