From: Fabio Estevam <fabio.este...@freescale.com>
When building imx_v6_v7_defconfig with imx-drm drivers selected as modules, we
get the following build errors:
ERROR: "irq_gc_mask_clr_bit" [drivers/staging/imx-drm/ipu-v3/imx-ipu-v3.ko]
undefined!
ERROR: "irq_gc_mask_set_bit" [drivers/staging/imx-drm/ipu-v3/imx-ipu-v3.ko]
undefined!
ERROR: "irq_gc_ack_set_bit" [drivers/staging/imx-drm/ipu-v3/imx-ipu-v3.ko]
undefined!
Export the required functions to avoid this problem.
