[RFC PATCH 0/2] dmaengine: at_hdmac: fix locking according to slave DMA requirements

Hi,

This is an attempt to solve the locking issue that we currently have with the
Atmel at_hdmac dmaengine driver.
I tested these patches with several drivers but may need more coverage before
making them permanent...

Comments welcome.

Nicolas Ferre (2):
  dmaengine: at_hdmac: remove the call to issue_pending from tx_status
  dmaengine: at_hdmac: run callback function with no lock held nor
    interrupts disabled
