Well this driver certainly has a talent for provoking the weirdest
bugs and reports
from the build robots.

The previous one was tricksy but clear in the end.

Now I feel puzzled again. Anyone has a clue? This symbol certainly isn't used
in the driver.

I know I've pleaded innocent before.

I can see the failure when I try the build (had a few setup hassles but
got something to work).

I get the following

WARNING: drivers/gpio/gpio-xgs-iproc.o(.data.rel+0x50): Section
mismatch in reference from the variable bcm_iproc_gpio_driver to the
variable .init.rodata:bcm_iproc_gpio_of_match
The variable bcm_iproc_gpio_driver references
the variable __initconst bcm_iproc_gpio_of_match
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the
variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

Yep that one is my bad. The fix from Mark will address it.

ERROR: "ia64_delay_loop" [drivers/net/phy/mdio-cavium.ko] undefined!
ERROR: "ia64_delay_loop" [drivers/spi/spi-thunderx.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:94: __modpost] Error 1
make: *** [Makefile:1303: modules] Error 2
make: *** Waiting for unfinished jobs....

I also get these when building commit 921d6c32b6f8 ("MAINTAINERS: Add
entry for RDA Micro GPIO driver and binding") so I think these were
probably introduced by a different commit but have been flagged because
of the error I introduced.
