Hi all,
Yet another error on devm_gpio_request_one()... Interestingly the
patch title says "export" but does not really export the symbol...
Thanks,
Fengguang

Yes, this patch subject is at best misleading. We really need to get
the EXPORT_SYMBOL patch merged.

Hi Fengguang,
The patch a291ede7be8359a8986740b11b93f9c80e40210b ' backlight-l4f00242t03-use-devm_gpio_request_one-fix'
is necessary to fix the export problem.
In my opinion, Andrew Morton will fold these patches as usual.
Thank you.
Best regards,
Jingoo Han

Err.. Sorry for the noise! This is a bit awkward situation. It seems
that I'll need to teach my scripts to detect the follow-up commits
with title "XXX-fix" and double check such commits before sending out
error reports.
Thanks,
Fengguang

I end up with a simple workaround: since Andrew already caught and fix
the problem, why should I bother again? Just skip it :-)
And it worked:
