Where is change_bit defined? I see __change_bit in
arch/arm/include/asm/bitops.h, but change_bit is defined as an extern
prototype. In Linux change_bit (without the __) is defined as an atomic
operation, which probably isn't appropriate here.
These two in particular could just be err_idx[i] ^= 3, right?

Increment i unconditionally.
