I have fixed most of the sparse warnings after converting __le32 to u32.
However am not able to address the following sparse warnings

	drivers/mtd/nand/raw/qcom_nandc.c:1401:29: sparse: warning: cast to restricted __le32
	drivers/mtd/nand/raw/qcom_nandc.c:1587:30: sparse: warning: cast to restricted __le32
	drivers/mtd/nand/raw/qcom_nandc.c:1588:31: sparse: warning: cast to restricted __le32
	drivers/mtd/nand/raw/qcom_nandc.c:1589:34: sparse: warning: cast to restricted __le32
	drivers/mtd/nand/raw/qcom_nandc.c:2479:47: sparse:    got restricted __le32 [usertype]
	drivers/mtd/nand/raw/qcom_nandc.c:2480:47: sparse:    got restricted __le32 [usertype]
	drivers/mtd/nand/raw/qcom_nandc.c:2616:25: sparse: warning: cast to restricted __le32
	drivers/mtd/nand/raw/qcom_nandc.c:2672:32: sparse: warning: cast to restricted __le32

These warnings are seen with existing kernel code too. For example

	drivers/mtd/ftl.c:299:39: sparse: warning: cast to restricted __le32
	drivers/mtd/ftl.c:387:23: sparse:    got restricted __le32 [usertype]

Hence, can these be ignored as false positives and post the next version of the patches.
Kindly advice.

Thanks
