Subject: pwm: tegra: Drop NUM_PWM macro
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=c009c56475a08fc8c0e1d4d4161bdcc76f3638b7;p=deliverable%2Flinux.git

pwm: tegra: Drop NUM_PWM macro

This macro is used to initialize the ->npwm field of the PWM chip. Use a
literal instead and make all other places rely on ->npwm.
