From: Uwe Kleine-König Date: Wed, 14 Feb 2024 09:33:24 +0000 (+0100) Subject: staging: greybus: pwm: Rely on pwm framework to pass a valid hwpwm X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9bda6a81ddaed8a61ca0211d6c14697177b98fbe;p=linux.git staging: greybus: pwm: Rely on pwm framework to pass a valid hwpwm The pwm framework already asserts to only pass a hwpwm value (= which) less than npwm (= pwmc->pwm_max + 1). So there is no need to recheck this condition. Drop the respective checks.
