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 suggestions from Coccinelle, e.g., drivers/pci/controller/dwc/pcie-visconti.c:286:2-9: line 286 is redundant because platform_get_irq() already prints an error Related: https://lore.kernel.org/all/20210310131913.2802385-1-kw@linux.com/ (local) https://lore.kernel.org/all/20200802142601.1635926-1-kw@linux.com/ (local) Signed-off-by: Krzysztof Wilczyński <redacted> --- drivers/pci/controller/dwc/pcie-visconti.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-)
