[1/1] spi: s3c64xx: set pointers to null using NULL rather than 0 commit: 845d3fd8a0aadf5dd97e6d345d3df4bf80099e69 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark

There are pointers being set to null using use. Use NULL instead. Signed-off-by: Colin Ian King <colin.i.king@gmail.com> --- drivers/spi/spi-s3c64xx.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-)
