![]() There is a strange interaction with drivers which use DMA if the cache starts off in a dirty state. Buffer space which the driver reads (but has not previously written) can contain zero bytes from alloc_priv(). This can cause corruption of the memory used by DMA for incoming data. Fix this and add a comment to explain the problem. This allows the dwc2 driver to work correctly with driver model, for example. Signed-off-by: Simon Glass <sjg@chromium.org> |
