[PATCH] spi: tegra20: fix build with CONFIG_PM_SLEEP=n

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

There is another one of these warnings:

drivers/spi/spi-tegra20-slink.c:1197:12: error: 'tegra_slink_runtime_resume' defined but not used [-Werror=unused-function]
 1197 | static int tegra_slink_runtime_resume(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~

Give it the same treatment as the other functions in this file.

Fixes: efafec27c565 ("spi: Fix tegra20 build with CONFIG_PM=n")
Fixes: 2bab94090b01 ("spi: tegra20-slink: Declare runtime suspend and resume functions conditionally")

That was actually done in efafec27c565. The error is the result of a bad
conflict resolution against 2bab94090b01, not a result of any of the
two patches listed in the Fixes: tags. So, yes, either this patch needs
to be applied in -next or the conflict resolution needs to be fixed.

Applied to

Thanks!

[1/1] spi: tegra20: fix build with CONFIG_PM_SLEEP=n
      commit: 7dc9b9562740d858332894447c9779b146559239

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

The problem has now been (re-)introduced into the mainline kernel
and causes various test build failures there.
