From 20555f098e487b98ee04bb33d8189e953275f8ae Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Fri, 8 Apr 2022 17:38:46 +0200 Subject: [PATCH] pwm: raspberrypi-poe: Fix endianness in firmware struct MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 09f688f0718f57f9cf68ee1aa94490f641e759ba ] The reg member of struct raspberrypi_pwm_prop is a little endian 32 bit quantity. Explicitly convert the (native endian) value to little endian on assignment as is already done in raspberrypi_pwm_set_property(). This fixes the following sparse warning: drivers/pwm/pwm-raspberrypi-poe.c:69:24: warning: incorrect type in initializer (different base types) drivers/pwm/pwm-raspberrypi-poe.c:69:24: expected restricted __le32 [usertype] reg drivers/pwm/pwm-raspberrypi-poe.c:69:24: got unsigned int [usertype] reg Fixes: 79caa362eab6 ("pwm: Add Raspberry Pi Firmware based PWM bus") Signed-off-by: Uwe Kleine-König Signed-off-by: Thierry Reding Signed-off-by: Sasha Levin --- drivers/pwm/pwm-raspberrypi-poe.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/pwm/pwm-raspberrypi-poe.c b/drivers/pwm/pwm-raspberrypi-poe.c index e52e29fc8231..6ff73029f367 100644 --- a/drivers/pwm/pwm-raspberrypi-poe.c +++ b/drivers/pwm/pwm-raspberrypi-poe.c @@ -66,7 +66,7 @@ static int raspberrypi_pwm_get_property(struct rpi_firmware *firmware, u32 reg, u32 *val) { struct raspberrypi_pwm_prop msg = { - .reg = reg + .reg = cpu_to_le32(reg), }; int ret;
