Subject: [PATCH] mmc: sdhci-esdhc-imx: comment runtime_pm_get_sync() in
 esdhc_prepare_tuning()

It is far from obvious what this is doing, and it looks like it's an
unbalanced runtime_pm_get() call.  However, the put is inside
sdhci_tasklet_finish(), so it's not unbalanced at all.  This should
be documented so people know what's going on here.  Do so.
