There is potential byte alignment problem on 32bits OS which will cause incorrect histogram blob id getting from the user space. This change fixes byte alignment problem on 32bits OS by keeping the struct members in one complete struct as the user space using. In previous code start address of 'info' would align to multiple of 8, so there would be 4 bytes padding between member 'event' and 'info' on 32 bits OS. It is affected by member 'base'. But user space just uses struct drm_msm_event_resp only, not affected by member 'base'. Driver code intends to send drm_msm_event_resp, but actually send unpacked members.
