[ Upstream commit 614b1868a125a0ba24be08f3a7fa832ddcde6bca ]
We just changed the code so we apply bias disable on the correct register but forgot to align the register calculation. The result is that we apply the change on the correct register, but possibly at the incorrect offset/bit
This went undetected because offsets tends to be the same between REG_PULL and REG_PULLEN for a given pin the EE controller. This is not true for the AO controller.
