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.

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.
