vga_in8() was storing the return value in tmp, but that return value was never used again. so it should be safe to remove those variables.
Signed-off-by: Sudip Mukherjee <[email protected]> --- just one doubt: vga_in8() is calling savage_in8() which is a readb(). so in effect we are reading one byte from (par->mmio.vbase + 0x8000 + 0x3da) and then discarding that value. so if we are discarding that value then why we are reading it? drivers/video/fbdev/savage/savagefb.h | 12 +++--------- 1 file changed, 3 insertions(+), 9 deletions(-) diff --git a/drivers/video/fbdev/savage/savagefb.h b/drivers/video/fbdev/savage/savagefb.h index dcaab90..8ff4ab1 100644 --- a/drivers/video/fbdev/savage/savagefb.h +++ b/drivers/video/fbdev/savage/savagefb.h @@ -351,32 +351,26 @@ static inline void VGAwSEQ(u8 index, u8 val, struct savagefb_par *par) static inline void VGAenablePalette(struct savagefb_par *par) { - u8 tmp; - - tmp = vga_in8(0x3da, par); + vga_in8(0x3da, par); vga_out8(0x3c0, 0x00, par); par->paletteEnabled = 1; } static inline void VGAdisablePalette(struct savagefb_par *par) { - u8 tmp; - - tmp = vga_in8(0x3da, par); + vga_in8(0x3da, par); vga_out8(0x3c0, 0x20, par); par->paletteEnabled = 0; } static inline void VGAwATTR(u8 index, u8 value, struct savagefb_par *par) { - u8 tmp; - if (par->paletteEnabled) index &= ~0x20; else index |= 0x20; - tmp = vga_in8(0x3da, par); + vga_in8(0x3da, par); vga_out8(0x3c0, index, par); vga_out8 (0x3c0, value, par); } -- 1.8.1.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
