[ Upstream commit e7e1e880b114ca640a2f280b0d5d38aed98f98c6 ]
Before the `callback_result` callback was introduced drivers coded their
invocation to the callback in a similar way to:
if (cb->callback) {
spin_unlock(&dma->lock);
cb->callback(cb->callback_param);
spin_lock(&dma->lock);
}
With the introduction of `callback_result` two helpers where introduced to
transparently handle both types of callbacks. And drivers where updated to
look like this:
if (dmaengine_desc_callback_valid(cb)) {
spin_unlock(&dma->lock);
dmaengine_desc_callback_invoke(cb, ...);
spin_lock(&dma->lock);
}
dmaengine_desc_callback_invoke() correctly handles both `callback_result`
and `callback`. But we forgot to update the dmaengine_desc_callback_valid()
function to check for `callback_result`. As a result DMA descriptors that
use the `callback_result` rather than `callback` don't have their callback
invoked by drivers that follow the pattern above.
Fix this by checking for both `callback` and `callback_result` in
dmaengine_desc_callback_valid().
Fixes:
