In case there are channels not paused during suspend (which on AT91 case is valid for serial driver when no_console_suspend boot argument is used) the at_xdmac_runtime_suspend_descriptors() was called more than one time due to at_xdmac_off(). To fix this add a new argument to at_xdmac_off() to specify if runtime PM reference counter needs to be decremented for queued active descriptors. Along with it moved the at_xdmac_runtime_suspend_descriptors() call under at_xdmac_chan_is_paused() check on suspend path as for the rest of channels the suspend is delayed by atmel_xdmac_prepare() in case channel is enabled. Same approach has been applied on resume path. Fixes: 650b0e99 ("dmaengine: at_xdmac: add runtime pm support") Signed-off-by:
