Subject: [PATCH v3] gpiolib: Add stubs for gpiod lookup table interface
Add stubs for gpiod_add_lookup_table() and gpiod_remove_lookup_table()
for the !GPIOLIB case to prevent build errors. Also add prototypes.
Signed-off-by: Anatolij Gustschin <ag...@denx.de>

Changes in v3:
- add stubs for !GPIOLIB case. Drop prototypes, these are
already in gpio/machine.h
Changes in v2:
- move gpiod_lookup_table out of #ifdef
