*	ASoC: codecs: wcd939x-sdw: Correct Soundwire ports mask	Krzysztof Kozlowski	2024-07-29	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Device has up to WCD939X_MAX_TX_SWR_PORTS (or WCD939X_MAX_RX_SWR_PORTS for sink) number of ports and the array assigned to prop.src_dpn_prop and prop.sink_dpn_prop has 0..WCD939X_MAX_TX_SWR_PORTS-1 elements. On the other hand, GENMASK(high, low) creates an inclusive mask between <high, low>, so we need the mask from 0 up to WCD939X_MAX_TX_SWR_PORTS-1. Theoretically, too wide mask could cause an out of bounds read in sdw_get_slave_dpn_prop() in stream.c, however only in the case of buggy driver, e.g. adding incorrect number of ports via sdw_stream_add_slave().

*	ASoC: codecs: wcd939x: Constify wcd939x_sdw_ch_info	Krzysztof Kozlowski	2024-06-18	1	-2/+2
\| \| \| \| \| \| \| \| \| \|	Driver does not modify static wcd939x_sdw_ch_info array, so it can be made const for code safety.

*	ASoC: codecs: Add WCD939x Soundwire devices driver	Neil Armstrong	2024-01-22	1	-0/+1551
	Add Soundwire Slave driver for the WCD9390/WCD9395 Audio Codec. The WCD9390/WCD9395 Soundwire devices will be used by the main WCD9390/WCD9395 Audio Codec driver to access registers and configure Soundwire RX and TX ports.
