This patch fixes an issue that is possible to set mismatch value to duty
for R-Car PWM if we input the following commands:
# cd /sys/class/pwm/<pwmchip>/
# echo 0 > export
# cd pwm0
# echo 30 > period
# echo 30 > duty_cycle
# echo 0 > duty_cycle
# cat duty_cycle
0
# echo 1 > enable
--> Then, the actual duty_cycle is 30, not 0.
So, this patch adds a condition into rcar_pwm_config() to fix this
issue.

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.
