I meant a dedicated var for 'fsl_lbc_ctrl_dev->regs'.
I.e.

regs = fsl_lbc_ctrl_dev->regs;
...
mxmr = &regs->mamr;
...
mxmr = &regs->mbmr;
..
mxmr = &regs->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?

Thanks,
