rtl2832_sdr_submit_urbs(), rtl2832_sdr_alloc_stream_bufs(), and rtl2832_sdr_alloc_urbs() are never called in atomic context. They call usb_submit_urb(), usb_alloc_coherent() and usb_alloc_urb() with GFP_ATOMIC, which is not necessary. GFP_ATOMIC can be replaced with GFP_KERNEL. This is found by a static analysis tool named DCNS written by myself. Signed-off-by:

drivers/video/fbdev/omap2/omapfb/dss/dss_features.c:895:2-5: WARNING: Use BUG_ON instead of if condition followed by BUG. Please make sure the condition has no side effects (see conditional BUG_ON definition in include/asm-generic/bug.h) Use BUG_ON instead of a if condition followed by BUG. Semantic patch information: This makes an effort to find cases where BUG() follows an if condition on an expression and replaces the if condition and BUG() with a BUG_ON having the conditional expression of the if statement as argument.

This patch adds a frontend driver for the Socionext/Panasonic MN884434 and MN884433 ISDB-S/T demodulators. The maximum and minimum frequency of MN88443x comes from ISDB-S and ISDB-T so frequency range is the following: - ISDB-S (BS/CS110 IF frequency, Local freq 10.678GHz) - Min: BS-1: 1032MHz - Max: ND24: 2070MHz - ISDB-T - Min: ch13: 470MHz - Max: ch62: 770MHz Signed-off-by:Katsuhiro Suzuki <suzuki.katsuhiro@socionext.com> Signed-off-by:

This patch adds I2C probe function to use dvb_module_probe() with this driver. And also support multiple delivery systems at the same device. Signed-off-by:

Each call to dw2102_probe() allocates memory by kmemdup for structures p1100, s660, p7500 and s421, but there is no their deallocation. dvb_usb_device_init() copies the corresponding structure into dvb_usb_device->props, so there is no use of original structure after dvb_usb_device_init(). The patch moves structures from global scope to local and adds their deallocation. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

A couple of drivers produced build errors after the mod_devicetable.h header was split out from the platform_device one, e.g. drivers/media/platform/davinci/vpbe_osd.c:42:40: error: array type has incomplete element type 'struct platform_device_id' drivers/media/platform/davinci/vpbe_venc.c:42:40: error: array type has incomplete element type 'struct platform_device_id' This adds the inclusion where needed. Fixes: ac316725 ("headers: separate linux/mod_devicetable.h from linux/platform_device.h") Signed-off-by:

The frequency step should take into account the tuner step, as, if tuner step is bigger than frontend step, the zigzag algorithm won't be doing the right thing, as it will be tuning multiple times at the same frequency. Signed-off-by: -

Right now, satellite frontend drivers specify frequencies in kHz, while terrestrial/cable ones specify in Hz. That's confusing for developers. However, the main problem is that universal frontends capable of handling both satellite and non-satelite delivery systems are appearing. We end by needing to hack the drivers in order to support such hybrid frontends. So, convert everything to specify frontend frequencies in Hz. Tested-by:

The USB completion callback does not disable interrupts while acquiring the lock. We want to remove the local_irq_disable() invocation from __usb_hcd_giveback_urb() and therefore it is required for the callback handler to disable the interrupts while acquiring the lock. The callback may be invoked either in IRQ or BH context depending on the USB host controller. Use the _irqsave() variant of the locking primitives.

Usually the format on the source pad is the same as on the sink pad. However the CSID is able to do some format conversions. To support this make the format on the source pad selectable amongst a list of formats. This list can be different for each sink pad format. This is still not used but will be when the format conversions are implemented. Signed-off-by:

Add support to output UYVY formats from the VFE (via the PIX interface). A configuration for the realign module in the VFE is added. As the realign module is present on 8x96 but not on 8x16, this is supported on 8x96 only. Signed-off-by:

There is a PM domain for each of the VFE hardware modules. Add support for basic runtime PM support to be able to control the PM domains. When a PM domain needs to be powered on - a device link is created. When a PM domain needs to be powered off - its device link is removed. This allows separate and independent control of the PM domains. Suspend/Resume is still not supported. Signed-off-by:
