[PATCH 4/5] Staging: sm750fb: Rename programModeRegisters

[Dorcas AnonoLitunya]

Rename function programModeRegisters to program_mode_registers. This
follows snakecase naming convention and ensures consistent naming style
throughout the file.Issue by checkpatch.

Mutes the following checkpatch error:
CHECK: Avoid CamelCase: <programModeRegisters>

[PATCH 5/5] Staging: sm750fb: Rename ddk750_setModeTiming

[Dorcas AnonoLitunya]

Rename function ddk750_setModeTiming to ddk750_set_mode_timing.This
patch affects three files as the function is imported to other external
files.

Renaming the function ensures snakecase naming convention is followed
thus enabling consistent naming style throughout.Issue by checkpatch.

Mutes the following checkpatch error:
CHECK:Avoid CamelCase: <ddk750_setModeTiming>
