media: netup_unidvb: drop initialization of PM pointers

2020-09-27T09:24:28Z

The .suspend() and .resume() callbacks are not defined for this driver. Thus, just the unlisting of PM pointers in the struct initializer will make no change in its behavior. Still unlisting is necessary so as to get rid of .suspend and .resume pointers as they are part of the legacy framework and should not be used in the driver code explicitly.

media: media/pci: prevent memory leak in bttv_probe

2020-09-26T08:55:55Z

In bttv_probe if some functions such as pci_enable_device, pci_set_dma_mask and request_mem_region fails the allocated memory for btv should be released. Signed-off-by: Xiaolong Huang Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: saa7134: use generic power management

2020-09-26T08:55:34Z

With the support of generic PM callbacks, drivers no longer need to use legacy .suspend() and .resume() in which they had to maintain PCI states changes and device's power state themselves. The required operations are done by PCI core. Compile-tested only. Signed-off-by: Vaibhav Gupta Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: pci: fix common ALSA DMA-mapping related codes

2020-09-26T08:34:44Z

The Documentation/DMA-API-HOWTO.txt states that dma_map_sg returns the numer of the created entries in the DMA address space. However the subsequent calls to dma_sync_sg_for_{device,cpu} and dma_unmap_sg must be called with the original number of entries passed to dma_map_sg. The sg_table->nents in turn holds the result of the dma_map_sg call as stated in include/linux/scatterlist.h. Adapt the code to obey those rules. While touching this code, update it to use the modern DMA_FROM_DEVICE definitions. Signed-off-by: Marek Szyprowski Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: av7110: don't do float point math

2020-09-12T07:39:37Z

It sounds that earlier versions of GCC have troubles when doing const math at compile time, if no typecast is used: on i386: ERROR: modpost: "__floatunsidf" [drivers/media/pci/ttpci/dvb-ttpci.ko] undefined! ERROR: modpost: "__ltdf2" [drivers/media/pci/ttpci/dvb-ttpci.ko] undefined! The warning was generated on gcc (SUSE Linux) 7.5.0. Gcc 9.2 compiles it fine. As an added bonus, it also fixes this objtool warning: drivers/media/pci/ttpci/av7110_v4l.c:163:11: error: SSE register return with SSE disabled Reported-by: Randy Dunlap Acked-by: Randy Dunlap Signed-off-by: Mauro Carvalho Chehab

media: ipu3-cio2: Drop bogus check and error message

2020-09-10T12:19:24Z

pcim_iomap_table() won't fail if previous pcim_iomap_regions() hasn't. Since we check pcim_iomap_regions() for failure the check close to pcim_iomap_table() is bogus and not needed. Signed-off-by: Andy Shevchenko Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab
