Hello,
this patch series brings fixes and improvements related to regmap access
for sc16is7xx and max310x drivers.

They are related to commit 3837a0379533 ("serial: sc16is7xx: improve regmap debugfs by using one regmap per port").

Patches 1 and 2 address some comments formulated during review of the
source patch listed above.

Patch 3 removes a structure member made obsolete.

Patches 4 and 5 are improvements for code readability.

Patches 6 and 7 port improvements from patches 4 and 5 of the sc16is7xx
driver over to the max310x driver.

I have tested the changes on a custom board with two SC16IS752 DUART over
a SPI interface using a Variscite IMX8MN NANO SOM. The four UARTs are
configured in RS-485 mode.

Thank you.
