We are derefencing pointers which are in the zero page, consequently gcc warns us with: drivers/hab/habv4.c: In function 'imx6_hab_get_status': drivers/hab/habv4.c:580:16: warning: array subscript 0 is outside array bounds of 'const struct habv4_rvt[0]' [-Warray-bounds] Yes, we really want to derefence these pointers, so silence the warning with OPTIMIZER_HIDE_VAR().
