Thanks for this, looks OK to me.
As this is a fix, can you add the following fixes tag?
Fixes: da76ba50963b ("PCI: tegra: Add power management support")
And whilst doing that can you rename the subject to "PCI: tegra: Fix return
value check of pm_runtime_get_sync" - it's slightly shorter and has the
word fix in the title.
Thanks,
Andrew Murray
