power: sysfs: Remove wakeup_abort_count attribute.

Commit Message

Ravi Chandra Sadineni July 22, 2019, 5:04 p.m. UTC

wakeup_abort_count and wakeup_count sysfs entries print the
same (wakeup_count) attribute. This patch removes the duplicate
wakeup_abort_count sysfs entry.

Isn't this the attribute you add back in a later patch?

If you have 2 patches that touch the same file, always make a patch
series so we have a chance to guess as to what patch comes first.

thanks,
