[PATCH v6 2/8] i2c: i801: Use GPIO_LOOKUP() helper macro

From: Geert Uytterhoeven
Date: Tue Mar 24 2020 - 09:57:30 EST


i801_add_mux() fills in the GPIO lookup table by manually populating an
array of gpiod_lookup structures. Use the existing GPIO_LOOKUP() helper
macro instead, to relax a dependency on the gpiod_lookup structure's
member names.

While this patch is a dependency for "[PATCH v6 4/8] gpiolib: Add
support for GPIO lookup by line name", it can be applied independently.
But an Acked-by would be nice, too.
