commit 3e2cf62efec52fb49daed437cc486c3cb9a0afa2 upstream.
In order to request dynamic allocationn of GPIO IDs, a negative number should be passed as a base GPIO ID via platform data. Unfortuntely, commit 771e53c4d1a1 ("ARM: OMAP1: ams-delta: Drop board specific global GPIO numbers") didn't follow that rule while switching to dynamically allocated GPIO IDs for Amstrad Delta latches, making their IDs overlapping with those already assigned to OMAP GPIO devices. Fix it.
