the code was looping, setting s_move[i] to the following calculations if (actual_step>= 0) s_move[i] = ((((i + 1) * gain + 0x200) - (i * gain + 0x200)) / 0x400); else s_move[i] = ((((i + 1) * gain - 0x200) - (i * gain - 0x200)) / 0x400); but, this code reduces to the expression s_move[i] = gain>> 10; The reason for the complexity was to generate a step function with integer division and rounding to land on specific values. But these calculations can be simplified to the following code: gain = ((actual_step<< 10) / 5)>> 10; for (i = 0; i<= 4; i++) s_move[i] = gain; Signed-off-by: Justin Madru<jdm64@gawab.com> Reviewed-by: Ray Lee<ray-lk@madrabbit.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> |
