[PATCH V2] media: s3c-camif: fix missing disable in tegra_adma_probe().

[PATCH V2] media: s3c-camif: fix missing disable in tegra_adma_probe().

[wu000273]

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")
Signed-off-by: Qiushi Wu <wu000273@umn.edu>

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.

I find such a change description still improvable (also according to
the shown combination of quotation characters).

You proposed a slightly different wording variant.

I suggest to delete the triple dashes before this diffstat.


I would find it nicer if you would put mail addresses from patch reviewers (like me)
also directly into the message field “Cc”.
