Subject: irqchip/irq-mvebu-gicp: Allocate enough memory for spi_bitmap
Git-commit: 478a2db82863db9f1c135111e78298e6ed5022f3
Patch-mainline: v4.13-rc1
References: fate#326470
BITS_TO_LONGS() gives us the number of longs we need, but we want to
allocate the number of bytes.
Fixes: a68a63cb4dfc ("irqchip/irq-mvebu-gicp: Add new driver for Marvell GICP")
