[PATCH v4 2/3] pinctrl: mcp23s08_spi: Simplify probe()

From: Biju Das
Date: Sun Oct 01 2023 - 11:01:29 EST


Simpilfy probe() by replacing device_get_match_data() and ID lookup for
retrieving match data by spi_get_device_match_data().

While at it, replace data type of variable type from 'int'->'unsigned int'
and declare variables following a reverse christmas tree order.
