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").
