This\nworks fine for DPU code (where most of the regions are aligned), but\nfails for snapshotting of the DSI data (because DSI data region is\nshifted by 4 bytes). Fix the code by removing length alignment and by\naccurately printing last registers in the region. While reworking the\ncode also fix the 16x memory overallocation in\nmsm_disp_state_dump_regs().\n\nPatchwork: https://patchwork.freedesktop.org/patch/725449/"
