Subject: [PATCH 0/6] Cleanup reads/writes to Line 6 device memory
Date: Tue, 10 Feb 2015 23:03:11 -0600 [thread overview]
Message-ID: <1423630997-25464-1-git-send-email-chris@rorvick.com> (raw)
The primary fix here is to throttle the requests for status after a
read or write operation. In some cases I was seeing more than 1000
before the device was ready with a response.
The remainder are smaller improvements related to the read/write logic.
All of this seems pretty straightforward with the possible exception of
changing the returned error from EINVAL to EIO. The EINVAL seems wrong
to me but maybe not?
Regards,
Chris
