The 'ahd_intr()' function contained a redundant comparisonthat was
always false. The comparison in question was:
if ((intstat == 0xFF) && (ahd->features & AHD_REMOVABLE) != 0)
The 'AHD_REMOVABLE' constant had a value of '0x00000'. Therefore, the
condition 'ahd->features & AHD_REMOVABLE' was always '0', making the
comparison unnecessary.
This patch removes the redundant comparison, making the code clearer
and more efficient.
