From e1a7d248279e375896cf53e9cb980032a84bf83e Mon Sep 17 00:00:00 2001 From: Martin Sperl Date: Tue, 9 Feb 2016 11:47:16 +0000 Subject: serial: bcm2835: fix unsigned int issue with irq Fixes error condition check when requesting the irq, that would not trigger because of uart_port.irq being defined as unsigned int.
