Follow-up to staging-prep-series + factory-drop-kernel-write: remove the BES2600_WRITE_DPD_TO_FILE-gated filp_open / kernel_read / kernel_write DPD file paths from bes_chardev.c, including the three functions, the no_dpd module_param, and the associated Makefile knob + three PATH macros (BES2600_DPD_PATH, BES2600_DEFAULT_DPD_PATH, BES2600_DPD_GOLDEN_PATH). Deployed + verified on ohm (srcversion C1283A24…): WiFi associated, KFENCE / sdio_tx_work splat / RX failure / PS Mode Error / factory cali data get failed = 0, no DPD regression. Net: -155 lines. Standalone single-patch series in both Mobian-paths and drivers/staging/bes2600/ paths variants, checkpatch --strict clean.
