Fix several bugs in the omap-dma driver's probe error and remove paths: missing return after failure, CPU PM notifier leaks and missing RCU synchronization, channels freed without stopping hardware, IRQs left enabled during teardown, descriptor pool destroyed too early, wrong interrupt register used in remove, and a flexible array conversion.
v3: Address remaining review comments: - Split CPU PM notifier fix into leak fix + RCU sync - Add missing return in probe error path - Guard IRQENABLE_L1 accesses for legacy platforms v2: Fix sashiko comments and add extra patch Rosen Penev (8): dmaengine: ti: omap-dma: fix missing return in probe error path dmaengine: ti: omap-dma: synchronize CPU PM notifier removal dmaengine: ti: omap-dma: fix CPU PM notifier leak dmaengine: ti: omap-dma: stop channels during teardown dmaengine: ti: omap-dma: disable IRQs on probe failure dmaengine: ti: omap-dma: destroy descriptor pool last dmaengine: ti: omap-dma: fix interrupt handling in remove dmaengine: ti: omap-dma: turn lch_map into a flexible array drivers/dma/ti/omap-dma.c | 122 +++++++++++++++++++++++--------------- 1 file changed, 74 insertions(+), 48 deletions(-) -- 2.54.0
