Subject: [PATCH] irqdomain: drop pointless NULL check in virq_debug_show_one
Date: Sun, 12 Nov 2017 22:29:03 +0100
Message-ID: <20171112212904.28574-1-linux@rasmusvillemoes.dk> (raw)

We've already done data->irq and data->hwirq, and also unconditionally
dereference data in the irq_data_get_irq_chip_data() call.
