dmaengine: pch_dma: fix memory leak on failure path in pch_dma_probe()

2015-04-17T18:11:46Z

Memory allocated for pch_dma is not deallocated in case of failure in pch_dma_probe(). Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov Signed-off-by: Vinod Koul

dmaengine: pch-dma: Rename device_control

2014-12-22T07:03:22Z

Rename the device_control callback of the Intel PCH DMA driver to terminate_all since it's all it's really doing. That will eventually be used to retrieve slave capabilities. Signed-off-by: Maxime Ripard Signed-off-by: Vinod Koul

drivers/dma/pch_dma: declare pch_dma_id_table as static

2014-12-05T17:58:30Z

pch_dma_id_table is used in pch_dma.c only, so declare it as static Signed-off-by: Michele Curti Signed-off-by: Vinod Koul

dmaengine: pch: fix compilation for alpha target

2014-05-22T13:20:49Z

commit 4828b493 introduced COMPILE_TEST for this driver and this cause compile failure on alpha as kzalloc wasnt availble for this arch in included header, so explictly add slab.h Reported-by: kbuild test robot Signed-off-by: Vinod Koul

dma: remove DEFINE_PCI_DEVICE_TABLE macro

2014-05-21T05:46:18Z

Don't use DEFINE_PCI_DEVICE_TABLE macro, because this macro is deprecated. Signed-off-by: Jingoo Han Acked-by: Andy Shevchenko Signed-off-by: Vinod Koul

dmaengine: pch_dma: use tasklet_kill in teardown

2014-03-17T13:04:11Z

As discussed in [1] the tasklet_disable is not a proper function for teardown. We need to ensure irq is disabled, followed by ensuring that don't schedule any more tasklets and then its safe to use tasklet_kill(). Here in pch dma driver we need to use free_irq() before tasklet_kill(). So move up the free_irq() which will ensure that the irq is disabled and also wait till all scheduled interrupts are executed by invoking synchronize_irq().

pch_dma: Add MODULE_DEVICE_TABLE

pch_dma: remove useless use of lock

2013-08-05T04:02:25Z

Accordingly to dma_cookie_status() description locking is not required. Signed-off-by: Andy Shevchenko Signed-off-by: Vinod Koul

pch_dma: fix error return code in pch_dma_probe()

2013-07-22T09:24:23Z

Fix to return -ENODEV when no proper base address found error handling case instead of 0, as done elsewhere in this function. Signed-off-by: Wei Yongjun Signed-off-by: Vinod Koul

pch_dma: Use GFP_ATOMIC because called from interrupt context

2013-04-15T04:21:16Z

pdc_desc_get() is called from pd_prep_slave_sg, and the function is called from interrupt context(e.g. Uart driver "pch_uart.c"). In fact, I saw kernel error message. So, GFP_ATOMIC must be used not GFP_NOIO. Signed-off-by: Tomoya MORINAGA Signed-off-by: Vinod Koul
