Remove surplus dev_err() when handing an error from platform_get_irq()

At the moment a lot of error handling code would print a duplicated error message should either the platform_get_irq() or platform_get_irq_byname() function fails to obtain an IRQ for a device.

There is no need to call the dev_err() function directly to print a custom message when handling an error from either of these functions as both are going to display an appropriate error message in case of a failure.

This series aims to remove surplus call to dev_err() when handing an error originating from either platform_get_irq() or platform_get_irq_byname() function as per suggestion from Coccinelle.

Related commits are commit 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()") and commit 98051ba2b28b ("coccinelle: Add script to check for platform_get_irq() excessive prints").

I squashed these together and applied them to pci/irq-error for v5.9, thanks!

The cover letter claims there should be 10 patches, but I only got 9. Just FYI.

Thank you!

There indeed should be 10 patches. I sent the missing one (not should why it didn't go through) this morning making sure it falls under the thread with the cover letter.

Sorry about that!

The missing patch can be seen here:

I picked up and applied 10/10 as well. And added Jesper & Ley Foon's reviewed-by and acked-by. Thanks!

There is no need to call the dev_err() function directly to print a custom message when handling an error from either the platform_get_irq() or platform_get_irq_byname() functions as both are going to display an appropriate error message in case of a failure.

This change is as per suggestion from Coccinelle:
