  Function dev_err() is redundant because platform_get_irq_byname()
already prints an error.

Also, platform_get_irq_byname() can't return 0 so ret <= 0
should be ret < 0.

Changes in v2:
  - Annotate patch with net-next.
  - Remove unnecessary comparison with zero.

Now that I've looked at this closely, it's not clear what
version of the code you are basing your patch on.

The current version of net-next/master, as well as the
current linus/master, do not include the message you
are removing.  This patch removed the message more than
a year ago:

   91306d1d131ee net: ipa: Remove useless error message

So at least the portion of your patch that removes the
message is unnecessary.

Meanwhile, it seems there is no need to check for a 0
return from platform_get_irq_byname(), but there is
no harm in doing so.

If you would like to send version 3 of this patch, which
would return what platform_get_irq_byname() returns if it
is less than 0 in gsi_irq_init(), I would be OK with that.

But please it on net-next/master.

Thanks.

Thank you for your precious feedback.

Yes, I think I mistakenly worked on the wrong branch..

Ok, I'll send v3 of this patch soon.
