Thank you.
I've applied this with the following tags added to the commit message:
Fixes: 57d0557dfa49 ("platform/x86: thinkpad_acpi: Add Thinkpad Edge E531 fan
support")
Reported-by: Dan Carpenter <dan.carpen...@linaro.org>
Closes:
https://lore.kernel.org/platform-driver-x86/f99e558d-c62a-41eb-93b3-cf00c016d907@stanley.mountain/
Thank you for your patch, I've applied this patch to my review-hans
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans
Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.
Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.
Regards,
Hans
