[PATCH] Drivers: hv: vmbus: include header for get_irq_regs()

From: Sebastian Andrzej Siewior
Date: Thu Aug 30 2018 - 03:55:13 EST

On !RT the header file get_irq_regs() gets pulled in via other header files. On
RT it does not and the build fails:

drivers/hv/vmbus_drv.c:975 implicit declaration of function âget_irq_regsâ [-Werror=implicit-function-declaration]
drivers/hv/hv.c:115 implicit declaration of function âget_irq_regsâ [-Werror=implicit-function-declaration]

Add the header file for get_irq_regs() in a common header so it used by
vmbus_drv.c by hv.c for their get_irq_regs() usage.
