I meant a dedicated var for 'fsl_lbc_ctrl_dev->regs'.
I.e.
regs = fsl_lbc_ctrl_dev->regs;
...
mxmr = ®s->mamr;
...
mxmr = ®s->mbmr;
..
mxmr = ®s->mcmr;
Instead of
mxmr = &fsl_lbc_ctrl_dev->regs->mamr;
...
mxmr = &fsl_lbc_ctrl_dev->regs->mbmr;
..
mxmr = &fsl_lbc_ctrl_dev->regs->mcmr;

Probably not as gcc will likely optimize it away,
but it's not needed, so why keep it there?
