Subject: pwm: Add a stub for devm_pwmchip_add()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=88da4e8113110d5f4ebdd2f8cd0899e300cd1954;p=linux.git

pwm: Add a stub for devm_pwmchip_add()

The devm_pwmchip_add() can be called by a module that optionally
instantiates PWM chip. In the case of CONFIG_PWM=n, the compilation
can't be performed. Hence, add a necessary stub.
