Video capture subdevs may be over I2C and may sleep during xfer, so we cannot do IRQ-disabled locking when calling the subdev. The IRQ-disabled locking is meant to protect the DMA queue list throughout the rest of the driver, so update the locking in [start|stop]_streaming to protect just this list, and update the irqlock comment to reflect what it actually protects.

In vpfe_s_fmt(), when the sensor format and the requested format were the same, bpp was assigned to vpfe->bpp without being initialized first. Grab the bpp value that is currently used by using __vpfe_get_format() instead of its wrapper, vpfe_try_fmt(). This use of uninitialized variable has been found by compiling the kernel with clang.

The adv7604 driver platform data contains fields for configuring the drive strength of the output pins. When probing the driver through DT these fields are not explicitly initialized, which means they are left at 0. This is a reserved setting for the drive strength configuration though and can cause signal integrity issues. Whether these signal integrity issues are visible depends on the PCB specifics (e.g. the higher the load capacitance for the output the more visible the issue). But it has been observed on existing solutions at high pixel clock rates. Initialize the drive strength settings to the power-on-reset value of the device when probing through devicetree to avoid this issue.
