Hi!

From: Anirudh Rayabharam <redacted>

[ Upstream commit fc6a6521556c8250e356ddc6a3f2391aa62dc976 ]

ath6kl_wmi_cmd_send could fail, so let's return its error code
upstream.

Something went very wrong here.

Content is okay, but "upstream commit" label is wrong, pointing to
incomplete fix that was reverted (with different content and different
author).

Yup, what ended up happening here is that my scripts got confused by the
reverted commit and the real fix having the same subject line. I've
fixed up my scripts and this patch was dropped. Thanks!
