return bits_data + bits_ecc;

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.
