PCI: dw-rockchip: Remove redundant dev_err()

[PATCH] PCI: dw-rockchip: Remove redundant dev_err()

Posted by Chen Ni 2 months, 1 week ago

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

           call?

Were any static source code analysis tools involved in the detection
of the presented change possibility?


By the way:
Such a patch can be generated also by the means of the semantic patch
language (Coccinelle software) for example.
