Subject: [PATCH 0932/1085] ASoC: bcm: Use the correct sample width value
|
||
|
|
||
|
ALSA's concept of the physical width of a sample is how much memory it
|
||
|
occupies, including any padding. This not the same as the count of bits
|
||
|
of actual sample content. In particular, S24_LE has a width of 24 bits
|
||
|
but a physical width of 32 bits because there is a byte of padding with
|
||
|
each sample.
|
||
|
|
||
|
When calculating bclk_ratio, etc., it is width that matters, not
|
||
|
physical width. Correct the error that has been replicated across the
|
||
|
drivers for many Raspberry Pi-compatible soundcards.
|
||
