From mboxrd@z Thu Jan 1 00:00:00 1970 From: rmk+kernel@armlinux.org.uk (Russell King) Date: Tue, 10 Jan 2017 22:53:28 +0000 Subject: [PATCH] gpio: mvebu: fix warning when building on 64-bit Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Casting a pointer to an int is not portable, and provokes a compiler warning. Cast to unsigned long instead to avoid the warning. drivers/gpio/gpio-mvebu.c: In function 'mvebu_gpio_probe': drivers/gpio/gpio-mvebu.c:662:17: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] soc_variant = (int) match->data; ^ This will be needed when building gpio-mvebu for Armada 7k/8k ARM64 SoCs. Signed-off-by: Russell King --- Linus, I don't think this is necessary to push into -rc, as its not yet used on ARM64 - GPIO support is not yet present in the DTS files, and the Kconfig doesn't allow the driver to be built on ARM64. Hence, please queue for the next merge window as a low priority fix.
