Subject: [PATCH] platform: use fwnode_irq_get_byname instead of
 of_irq_get_byname to get irq

Not only platform devices described by OF have named interrupts, but
devices described by ACPI also have named interrupts. The fwnode is an
abstraction to different standards, and using fwnode_irq_get_byname can
support more devices.

It's the middle of the merge window, we can't do anything until after
6.1-rc1 is out, please relax and wait for that.

And what is the rush here, what is broken without this change?

thanks,

Got it, just wondering if there anything I could improve in this patch,
since I have not got any feedback. The bug just affect named interrupts in
ACPI, which seems not used widely and not in a hurry.

Your patch is corrupted and can not be applied :(
You could have tested this by picking it up from lore.kernel.org and
verified that it worked.

Please fix your email client and send a new version.

I sent a PATCH v2* several days before. This patch's format should be
good and I removed a meaningless if-branch.

Hi,

This is the friendly patch-bot of Greg Kroah-Hartman.  You have sent him
a patch that has triggered this response.  He used to manually respond
to these common problems, but in order to save his sanity (he kept
writing the same thing over and over, yet to different people), I was
created.  Hopefully you will not take offence and will fix the problem
in your patch and resubmit it so that it can be accepted into the Linux
kernel tree.

You are receiving this message because of the following common error(s)
as indicated below:

- Your patch is malformed (tabs converted to spaces, linewrapped, etc.)
  and can not be applied.  Please read the file,
  Documentation/email-clients.txt in order to fix this.

- Your patch was attached, please place it inline so that it can be
  applied directly from the email message itself.

If you wish to discuss this problem further, or you have questions about
how to resolve this issue, please feel free to respond to this email and
Greg will reply once he has dug out from the pending patches received
from other developers.

thanks,

greg k-h's patch email bot
