These were merged for 6.5 but the corresponding sanity check for regmap
has now been included in 6.4-rc5 which consequently breaks these codecs
(similar for wcd938x-sdw):

[   11.443485] wsa883x-codec sdw:0:0217:0202:00:1: error -ENOTSUPP: regmap_init failed
[   11.443525] wsa883x-codec sdw:0:0217:0202:00:1: Probe of wsa883x-codec failed: -524
[   11.443554] wsa883x-codec: probe of sdw:0:0217:0202:00:1 failed with error -52

Is it possible to get also these fixes into 6.4 final?
