Subject: Input: pwm-beeper - suppress error message on probe defer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=62481881401246859d9bd06b7c7b9a391c78892c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Input: pwm-beeper - suppress error message on probe defer

This suppress printing an error message when pwm_get returns -EPROBE_DEFER.
Otherwise you get a bunch of noise in the kernel log.
