tegra_sflash_probe() The platform_get_irq might be failed and return a negative result. So there should have an error handling code. Fixed this by adding an error handling code.

2023-07-26spi: spi-qcom-qspi: Add mem_ops to avoid PIO for badly sized readsDouglas Anderson1-0/+25
In the patch ("spi: spi-qcom-qspi: Fallback to PIO for xfers that aren't multiples of 4 bytes") we detect reads that we can't handle properly and fallback to PIO mode. While that's correct behavior, we can do better by adding "spi_controller_mem_ops" for our controller. Once we do this then the caller will give us a transfer that's a multiple of 4-bytes so we can DMA.

2023-07-26spi: spi-qcom-qspi: Fallback to PIO for xfers that aren't multiples of 4 bytesDouglas Anderson1-0/+12
The Qualcomm QSPI driver appears to require that any reads using DMA are a mutliple of 4 bytes. If this isn't true then the controller will clobber any extra bytes in memory following the last word. Let's detect this and falback to PIO. This fixes problems reported by slub_debug=FZPUA, which would complain about "kmalloc Redzone overwritten". One such instance said: 0xffffff80c29d541a-0xffffff80c29d541b @offset=21530. First byte 0x0 instead of 0xcc Allocated in mtd_kmalloc_up_to+0x98/0xac age=36 cpu=3 pid=6658 Tracing through what was happening I saw that, while we often did DMA tranfers of 0x1000 bytes, sometimes we'd end up doing ones of 0x41a bytes. Those 0x41a byte transfers were the problem. NOTE: a future change will enable the SPI "mem ops" to help avoid this case, but it still seems good to add the extra check in the transfer.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree.
