In msi2500_stop_streaming(), there is an if statement on line 870 to check whether dev->udev is NULL: if (dev->udev) When dev->udev is NULL, it is used on line 877: msi2500_ctrl_msg(dev, CMD_STOP_STREAMING, 0) usb_control_msg(dev->udev, usb_sndctrlpipe(dev->udev, 0), ...) Thus, a possible null-pointer dereference may occur. To fix this bug, dev->udev is checked before calling msi2500_ctrl_msg(). This bug is found by a static analysis tool STCheck written by us.

Each iteration of for_each_child_of_node puts the previous node, but in the case of a goto from the middle of the loop, there is no put, thus causing a memory leak. Hence add a new label that puts the last used node, and edit the goto statements in the middle of the loop to first go to the new label. Issue found with Coccinelle. Signed-off-by:

As reported on: https://lore.kernel.org/linux-media/20190627222020.45909-1-willemdebruijn.kernel@gmail.com/ if gp8psk_usb_in_op() returns an error, the status var is not initialized. Yet, this var is used later on, in order to identify: - if the device was already started; - if firmware has loaded; - if the LNBf was powered on. Using status = 0 seems to ensure that everything will be properly powered up. So, instead of the proposed solution, let's just set status = 0. Reported-by:

The SDM630/660 SoCs (and variants) have another clock source for the PHY, which must be set to a rate that's equal or greater than the CSI PHY timer clock: failing to do this will produce PHY overflows when trying to get a stream from a very high bandwidth camera sensor and outputting no frame or a partial one. Since I haven't found any usecase in which the csiX_phy clock needs to be higher than the csiXphy_timer, let's just set the same rate on both, which seems to work just perfect. Signed-off-by:

Add support for the Qualcomm SDM630/636/660 and SDA variants' camera subsystem. These SoCs are equipped with: - 3x CSI PHY 3-Phase v1.0 (downstream csiphy-v3.5) - 4x CSID v5.0 - 2x ISPIF v3.0 - 2x VFE 4.8 As a note, this camera subsystem is very similar to the one that is found in the MSM8998/APQ8098 SoCs.

Add the support for VFE 4.8 in the camss-vfe-4-7 driver, as this one really is a minor revision, requiring the very same management and basically having the same register layout as VFE 4.7, but needing a different QoS and DS configuration, using a different register to enable the wm and habing the same UB size for both instances (instead of a different size between instance 0 and 1).

In preparation to add support for VFE 4.8, rename these functions by adding the vfe version that they are referred to (for example, vfe_get_ub_size -> vfe47_get_ub_size), as these are the only ones that will be different for the VFE version 4.8. Signed-off-by:

Resetting the ISPIF VFE0 context is wrong if we are using the VFE1 for dual-camera or simply because a secondary camera is connected to it: in this case the reset will always happen on the VFE0 ctx of the ISPIF, which is .. useless. Fix this usecase by adding the ISPIF_RST_CMD_1 address and choose where to do the (or what to) reset based on the VFE line id. Signed-off-by:

This allows the timeout to be set with the LIRC_SET_REC_TIMEOUT ioctl. The timeout was hardcoded at just over 20ms, but returned 120ms when queried with the LIRC_GET_REC_TIMEOUT ioctl. This also ensures the idle threshold is set correctly with a base clock other than 8Mhz. Acked-by:

If a user holds a button down on a remote, then no ir idle interrupt will be generated until the user releases the button, depending on how quickly the remote repeats. No IR is processed until that point, which means that holding down a button may not do anything. This also resolves an issue on a Cubieboard 1 where the IR receiver is picking up ambient infrared as IR and spews out endless "rc rc0: IR event FIFO is full!" messages unless you choose to live in the dark.

Add support of BT656 embedded synchronization bus. This mode allows to save hardware synchro lines hsync & vsync by replacing them with synchro codes embedded in data stream. This bus type is only compatible with 8 bits width data bus. Due to reserved values 0x00 & 0xff used for synchro codes, valid data vary from 0x1 to 0xfe, this is up to sensor to clip accordingly pixel data. As a consequence of this clipping, JPEG is not supported with this bus type. DCMI crop feature is also not available with this bus type. Signed-off-by:

Add support of BT656 embedded synchronization bus mode in DCMI driver. Add "bus-type" property and make it required so that there is no ambiguity between parallel mode (bus-type=5) and BT656 mode (bus-type=6). BT656 mode allows to save hardware synchro lines hsync & vsync by replacing them with synchro codes embedded in data stream, hence hsync-active & vsync-active properties are useless in this mode. With DCMI, BT656 bus mode is only compatible with 8 bits width data bus. Signed-off-by:
