Embedded systems often connect to sensors or other multimedia subdevices directly. Currently, to be able to select such a subdevice (e.g. CONFIG_VIDEO_OV5640) disabling of the auto- select config option is needed (CONFIG_MEDIA_SUBDRV_AUTOSELECT). This is inconvenient as the ancillary drivers for a particular device then need to be selected manually. Allow to select drivers manually while keeping the auto-select feature in case EXPERT (selected by EMBEDDED) is enabled. Signed-off-by:

The size argument of the alloc memop, which allocates buffer memory, is page aligned. Document it as such in the only caller as well as ops documentation. Signed-off-by:

buf->size is an unsigned long; casting that to int will lead to an overflow if buf->size exceeds INT_MAX. Fix this by changing the type to unsigned long instead. This is possible as the buf->size is always aligned to PAGE_SIZE, and therefore the size will never have values lesser than 0. Note on backporting to stable: the file used to be under drivers/media/v4l2-core, it was moved to the current location after 4.14. Signed-off-by:

PAGE_ALIGN() may wrap the buffer size around to 0. Prevent this by checking that the aligned value is not smaller than the unaligned one. Note on backporting to stable: the file used to be under drivers/media/v4l2-core, it was moved to the current location after 4.14. Signed-off-by:

The ipu3 GDC function need some envelope to do filtering and the minimal envelope size(GDC in - out) for ipu3 should be 4. Current value 4 was defined for older version GDC, this patch correct it. Signed-off-by:

No need for a high-accuracy delay here as long as it is more than 2 milliseconds this should be ok - as it is non-atomic context it will be not be precise 2 milliseconds so giving the hrtimer subsystem 50 microseconds to merge timers and reduce interrupts. Signed-off-by:

The commit 05fed816 ("[media] marvell-ccic: add MIPI support for marvell-ccic driver") that claimed to add CSI2 turned on C0_EOF_VSYNC for parallel bus without a very good explanation. That broke camera on OLPC XO-1.75 which precisely uses a sensor on a parallel bus. Revert that chunk. Tested on an OLPC XO-1.75.

The commit d790b7ed ("[media] vb2-dma-sg: move dma_(un)map_sg here") left dma_desc_nent unset. It previously contained the number of DMA descriptors as returned from dma_map_sg(). We can now (since the commit referred to above) obtain the same value from the sg_table and drop dma_desc_nent altogether. Tested on OLPC XO-1.75 machine. Doesn't affect the OLPC XO-1's Cafe driver, since that one doesn't do DMA.

If the v4l2 controls are set up for autofoo/foo-type handling by calling v4l2_ctrl_auto_cluster() with the last set_volatile argument setting true, each non-auto control doesn't need to be flagged V4L2_CTRL_FLAG_VOLATILE.

Setting the value of the V4L2_CID_VFLIP control is currently ignored. Because V4L2_CID_HFLIP and V4L2_CID_VFLIP are independently controlled in s_ctrl() but these controls belong to the same cluster and the first control is V4L2_CID_HFLIP. Fix it by not clustering these controls. Also correct erroneous updating register bit for vertical flip.

Some displays pull down the HPD when in standby, but CEC is still active and the display can be woken up by sending an Image View On or Text View On CEC command. The CEC specification doesn't tell you what the initiator should be for such a command (without a HPD it's unclear if the CEC adapter can claim a logical address). This patch allows any initiator value when there is no HPD for the Image/Text View On commands and for the Ping command. Signed-off-by:

Due to limitations in gpiolib it was impossible to disable the interrupt of an input gpio and then switch it to gpio output and drive it. The only way to achieve that was to free the interrupt first, then switch the direction. When going back to gpio input and using interrupts to read the gpio pin you had to request the irq again. This limitation was lifted in gpiolib in kernel 4.20, but the cec-gpio driver was still using the old workaround implementation. This patch updates the cec-gpio driver to just enable and disable the irq. Signed-off-by:

The cec device node can be used right after it was created, but that leaves a race condition where the device was created, but devnode->registered was still false. So an ioctl() would result in an error. So set it to true before calling cdev_device_add() and to false again if cdev_device_add returned an error. Signed-off-by:

actual_length != wlen is the only error path which does not generate an error message. Adding an error message here allows to report a more specific error and to remove the error reporting from the call sites. Also clean up the error paths - in case of an error, the remaining code is skipped, and ret is returned. Skip setting ret and return immediately (no cleanup necessary). Signed-off-by:
