Subject[PATCH 4.18 062/197] platform/x86: intel_punit_ipc: fix build errors
4.18-stable review patch.  If anyone has any objections, please let me know.


From: Randy Dunlap <>

[ Upstream commit 340fd4cff43f18bace9358d4decdc9b6ed0715be ]

Fix build errors by #including <linux/io.h>.

../drivers/platform/x86/intel_punit_ipc.c: In function 'ipc_read_status':
../drivers/platform/x86/intel_punit_ipc.c:55:2: error: implicit declaration of function 'readl' [-Werror=implicit-function-declaration]
return readl(ipcdev->base[type][BASE_IFACE]);
../drivers/platform/x86/intel_punit_ipc.c: In function 'ipc_write_cmd':
../drivers/platform/x86/intel_punit_ipc.c:60:2: error: implicit declaration of function 'writel' [-Werror=implicit-function-declaration]
writel(cmd, ipcdev->base[type][BASE_IFACE]);
