irqchip/tegra: Fix overflow implicit truncation warnings
Fix -Woverflow warnings for tegra irqchip driver which is a result of moving arm64 custom MMIO accessor macros to asm-generic function implementations giving a bonus type-checking now and uncovering these overflow warnings. drivers/irqchip/irq-tegra.c: In function ‘tegra_ictlr_suspend’: drivers/irqchip/irq-tegra.c:151:18: warning: large integer implicitly truncated to unsigned type [-Woverflow] writel_relaxed(~0ul, ictlr + ICTLR_COP_IER_CLR); ^ Suggested-by: Marc Zyngier <maz@kernel.org> Signed-off-by: Sai Prakash Ranjan <quic_saipraka@quicinc.com> Reviewed-by: Arnd Bergmann <arnd@arndb.de> Cc: Marc Zyngier <maz@kernel.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
