[PATCH 5.4 17/92] serial: 8250_dw: Avoid double error messaging when IRQ absent

[Greg Kroah-Hartman]

From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

commit 05faa64e73924556ba281911db24643e438fe7ba upstream.

Since the commit 7723f4c5ecdb ("driver core: platform: Add an error message
to platform_get_irq*()") platform_get_irq() started issuing an error message.
Thus, there is no need to have the same in the driver

Fixes: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()")
