reg_addr->reg_report_rate is supposed to exist in M06, not M09. The driver is written to skip avoids access to non-existing registers when the register address is NO_REGISTER (0xff). But reg_addr->reg_report_rate is initialized to 0x00 by devm_kzalloc() (in edt_ft5x06_ts_probe()) and not changed thereafter. So the checks do not work and an access to register 0x00 is done. Fix by setting reg_addr->reg_report_rate to NO_REGISTER. Also fix the only place where reg_report_rate is checked against zero instead of NO_REGISTER.

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.
