Subject: pwm: Silently error out on EPROBE_DEFER
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=93c292ef3cbb46db78853763fc4d9a5b9dfb97d5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

pwm: Silently error out on EPROBE_DEFER

In of_pwm_get(), if we fail to get the PWM chip due to probe deferal, we
shouldn't print an error message. Just be silent in this case.
