The ov5647_read() functions calls i2c_master_send() and i2c_master_read() in sequence. However this leaves space for other clients to contend the bus and insert an unrelated transaction in between the two calls. Replace the two calls with a single i2c_transfer() one, that locks the bus in between the transactions.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
