OF: /sound: Read of boolean property 'simple-audio-card,frame-master' with a value. or: OF: /soc/sound@ec500000/ports/port@0/endpoint: Read of boolean property 'bitclock-master' with a value. OF: /soc/sound@ec500000/ports/port@0/endpoint: Read of boolean property 'frame-master' with a value. The use of of_property_read_bool() for non-boolean properties is deprecated in favor of of_property_present() when testing for property presence. Replace testing for presence before calling of_property_read_u32() by testing for an -EINVAL return value from the latter, to simplify the code. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- Seen since commit c141ecc3cecd7647 ("of: Warn when of_property_read_bool() is used on non-boolean properties") in dt-rh/for-next. I could not exercise all code paths, so review/testing would be appreciated. Thanks! --- sound/soc/soc-core.c | 32 +++++++++++++------------------- 1 file changed, 13 insertions(+), 19 deletions(-)
