Subject: [PATCH] drivers/watchdog/Kconfig: Let XILINX_WATCHDOG and TEGRA_WATCHDOG depend on HAS_IOMEM

They need HAS_IOMEM, so let them depend on it, the related error (with
allmodconfig under um):

Sorry, the line above is useless for this issue, please skip it.

Thanks.

Headline is a bit excessive ("watchdog: ..." would have been sufficient,
the first error is irrelevant as you found out yourself, and you got an
extra empty line here. Otherwise looks good.

Can you resubmit with that fixed ?

On a side note, guess the conclusion was to not provide a dummy for
devm_ioremap_resource if HAS_IOMEM is not defined. Too bad.

OK, thank, I shall send patch v2 for it.

For me, it is checked during config time, so need report error during
compiling or building time instead of dummy.

And I'd like to let devm_ioremap* quoted by "#if HAS_IOMEM", so can
find this issue during compiling time, not in linking time (which can
save builder's time resource).


Thanks.
