From: Qiushi Wu <wu000273@umn.edu>

"pm_runtime_enable()" was not handled by "pm_runtime_disable()"
after a call of the function “pm_runtime_get_sync()” failed.
Thus move the jump target “err_pm” before calling function 
"calling pm_runtime_disable()".

Fixes: babde1c243b2 ("[media] V4L: Add driver for S3C24XX/S3C64XX SoC series camera interface")

Thanks for the patch. It seems you have got typo in the subject line.
With tegra_adma_probe changed to s3c_camif_probe feel free to add:

I just noticed this patch https://patchwork.linuxtv.org/patch/63976
which includes your fix and handles one more issue. Thus it might be
better to apply the patch from Dinghao Liu instead.
