[1/1] spi: mpc5xxx-psc: Fix unsigned expression compared with zero commit: de5e92cb5cefd2968b96075995a36e28298edf71 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 is two warnings reported by coccinelle: ./drivers/spi/spi-mpc512x-psc.c:493:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0 ./drivers/spi/spi-mpc52xx-psc.c:332:5-13: WARNING: Unsigned expression compared with zero: mps -> irq < 0 The commit "208ee586f862" ("spi: mpc5xxx-psc: Return immediately if IRQ resource is unavailable") was to check whether the IRQ resource is unavailable. When the IRQ resource is unavailable, an error code is returned, however, the type of "mps->irq" is "unsigned int", causing the error code to flip. Modify the type of "mps->irq" to solve this problem.
