Removes unused functions and files ddk750_sii164. Functions were used in ddk750_dvi.c, which is itself unused. Removal will be in the second patch in the series. Signed-off-by: Ruben Wauters <rubenru09@aol.com> --- I have checked the entire driver, and found that the code present within these files is used nowhere (except for in ddk750_dvi.c, which is also used nowhere). As such I have decided to remove the code in this file, as it is essentially deadcode. --- drivers/staging/sm750fb/Makefile | 4 +- drivers/staging/sm750fb/ddk750_dvi.c | 21 +- drivers/staging/sm750fb/ddk750_sii164.c | 408 ------------------------ drivers/staging/sm750fb/ddk750_sii164.h | 174 ---------- 4 files changed, 4 insertions(+), 603 deletions(-) delete mode 100644 drivers/staging/sm750fb/ddk750_sii164.c delete mode 100644 drivers/staging/sm750fb/ddk750_sii164.h
