pwm: raspberrypi-poe: Fix endianness in firmware struct
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 <u.kleine-koenig@pengutronix.de> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
