This error apparently is caused by timed out event, so a -ETIMEDOUT
should be used instead of a -EIO, and it also tells user what happened
, so this dev_err may not be needed anymore.

I used ./scripts/get_maintainer.pl to get maintainers about this file,
I thought this script searches maintainers with looking up MAINTAINER,
is that right?
So I searched MAINTAINER and also found nothing related to hmc5843.
In the declearation area I can see Shubhrajyoti Datta
<shubhrajyoti@xxxxxx> wroted this driver and several other people
including Peter Meerwald have contributed. Is this driver now a orphan?
Or if it is, I think we may also need to add it to the MAINTAINER file.
I'm also familiar with this device, I think I can add interrupt support
later.
