Subject: [PATCH 00/10] Remove surplus dev_err() when handing an error from platform_get_irq()
Date: Sun,  2 Aug 2020 14:25:52 +0000	[thread overview]
Message-ID: <20200802142601.1635926-1-kw@linux.com> (raw)

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").
