From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Add #include <linux/slab.h> to fix build errors. This driver uses kzalloc() and kfree() so it needs to #include the appropriate header file for those interfaces. Fixes these build errors: ../drivers/media/platform/cadence/cdns-csi2rx.c: In function 'csi2rx_probe': ../drivers/media/platform/cadence/cdns-csi2rx.c:421:2: error: implicit declaration of function 'kzalloc' [-Werror=implicit-function-declaration] csi2rx = kzalloc(sizeof(*csi2rx), GFP_KERNEL); ../drivers/media/platform/cadence/cdns-csi2rx.c:421:9: warning: assignment makes pointer from integer without a cast [enabled by default] csi2rx = kzalloc(sizeof(*csi2rx), GFP_KERNEL); ../drivers/media/platform/cadence/cdns-csi2rx.c:466:2: error: implicit declaration of function 'kfree' [-Werror=implicit-function-declaration] kfree(csi2rx); Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Cc: Maxime Ripard <maxime.ripard@xxxxxxxxxxx> --- drivers/media/platform/cadence/cdns-csi2rx.c | 1 + 1 file changed, 1 insertion(+) --- linux-next-20180608.orig/drivers/media/platform/cadence/cdns-csi2rx.c +++ linux-next-20180608/drivers/media/platform/cadence/cdns-csi2rx.c @@ -13,6 +13,7 @@ #include <linux/of_graph.h> #include <linux/phy/phy.h> #include <linux/platform_device.h> +#include <linux/slab.h> #include <media/v4l2-ctrls.h> #include <media/v4l2-device.h>
