In 'commit 295ab497d6 ("[media] media: platform: pxa_camera: make
printk consistent")' a pointer to the device structure in
mclk_get_divisor() was changed to pcdev_to_dev(pcdev). The pointer used
by pcdev_to_dev() is still uninitialized during the call to
mclk_get_divisor() as it happens in v4l2_device_register() at the end
of the probe. The dev_warn and dev_dbg caused a line in the log:
(NULL device *): Limiting master clock to 26000000
Fix this by using an initialized pointer from the platform_device
(as before the old patch).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
