Use io relaxed access memory primitives to satisfy strict type checking (__force). This will fix some existing sparse warnings: sparse: warning: cast to restricted __le32 Signed-off-by: Rui Miguel Silva <rui.silva@linaro.org> --- drivers/usb/isp1760/isp1760-hcd.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
