The function releases the queue if the file being released is the queue owner. The check reads the queue->owner field without taking the queue lock, creating a race condition with functions that set the queue owner, such as vb2_ioctl_reqbufs() for instance. Fix this by moving the queue->owner check within the mutex protected section. Signed-off-by:

The vb2_fop_poll() implementation tries to be clever on whether it needs to lock the queue mutex by checking whether polling might start fileio. The test requires reading the q->num_buffer field, which is racy if we don't hold the queue mutex in the first place. Remove the extra cleverness and just lock the mutex. Signed-off-by:

Add support for selection target V4L2_SEL_TGT_NATIVE_SIZE. It is equivalent of what V4L2_SEL_TGT_CROP_BOUNDS used to be. Support for V4L2_SEL_TGT_CROP_BOUNDS is still supported by the driver as a compatibility interface. Signed-off-by:

This extends the precalculated tpg_csc_colors matrix with AdobeRGB and BT.2020 colorspace support. It also adds two precalculated tables that convert between linear RGB and non-linear Rec.709 R'G'B' values, i.e. the Rec. 709 transfer function. This is needed to efficiently handle the BT.2020 Constant Luminance Yc'CbcCrc encoding and decoding. Signed-off-by:

Beniamino Galvani authored
Amlogic Meson SoCs include a infrared remote control receiver that can operate in two modes: "NEC" mode in which the hardware decodes frames using the NEC IR protocol, and "general" mode in which the receiver simply reports the duration of pulses and spaces for software decoding. This is a driver for the IR receiver that implements software decoding of received frames. Signed-off-by:

According with Malcolm, the missing breaks are intentional. So, let's revert commit d442b15f, add some comments to document it and fix the two smatch warnings: drivers/media/usb/dvb-usb-v2/lmedm04.c:828 lme_firmware_switch() warn: missing break? reassigning 'st->dvb_usb_lme2510_firmware' drivers/media/usb/dvb-usb-v2/lmedm04.c:850 lme_firmware_switch() warn: missing break? reassigning 'st->dvb_usb_lme2510_firmware' using a different strategy to avoid reassign values to st->dvb_usb_lme2510_firmware.
