[PATCH] ahd: Remove Redundant Comparison in ahd_intr()

[PATCH] ahd: Remove Redundant Comparison in ahd_intr()

[Rand Deeb]

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.
