Subject: [PATCH 03/10] PCI: tegra: Remove dev_err() when handing an error from platform_get_irq()
Date: Sun,  2 Aug 2020 14:25:55 +0000	[thread overview]
Message-ID: <20200802142601.1635926-4-kw@linux.com> (raw)
In-Reply-To: <20200802142601.1635926-1-kw@linux.com>

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:

  drivers/pci/controller/pci-tegra.c:1524:2-9: line 1524 is redundant
  because platform_get_irq() already prints an error

  drivers/pci/controller/pci-tegra.c:1742:2-9: line 1742 is redundant
  because platform_get_irq() already prints an error
