[PATCH v3 5/6] asus-wmi: Convert all attr-show to use sysfs_emit
Posted by Luke D. Jones 3 years, 8 months ago
This changes all *_show attributes in asus-wmi.c to use sysfs_emit()
instead of the older method of writing to the output buffer manually.

This looks good to me,

(Carry the tag with a new version of the series in this patch)

Hans, I guess this one can be applied so it will be less of a burden
on reviewing the rest.

Thanks for the review. I agree that this one can be merged
already, so I have just merged it:

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.

Patches which are added to review-hans now are intended for
the next rc1. This branch will get rebased to the next rc1 when
it is out and after the rebasing the contents of review-hans
will be pushed to the platform-drivers-x86/for-next branch.

Regards,

Hans
