Jonathan Bell e34d093f50 spi: dw: don't immediately kill DMA transfers if an error occurs
Disabling the peripheral resets controller state which has a dangerous
side-effect of disabling the DMA handshake interface while it is active.
This can cause DMA channels to hang.

The error recovery pathway will wait for DMA to stop and reset the chip
anyway, so mask further FIFO interrupts and let the transfer finish
gracefully.

Linux kernel

There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first.

In order to build the documentation, use make htmldocs or make pdfdocs. The formatted documentation can also be read online at:

https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
