Subject: [PULL 01/17] hw/gpio/max7310: Remove impossible check
Date: Sat, 19 Sep 2020 20:44:35 +0200	[thread overview]
Message-ID: <20200919184451.2129349-2-laurent@vivier.eu> (raw)
In-Reply-To: <20200919184451.2129349-1-laurent@vivier.eu>

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

The max7310_gpio_set() handler is static and only used by
qdev_init_gpio_in, initialized with 8 IRQs. The 'line'
argument can not be out of the [0-8[ range.
Replace the dead code by an assertion.
