6.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Peter Ujfalusi peter.ujfalusi@linux.intel.com
commit 816f291fc23f325d31509d0e97873249ad75ae9a upstream.
SSP/DMIC blobs have no support for FLOAT type, they are using S32 on data bus.
Convert the format from FLOAT_LE to S32_LE to make sure that the correct format is used within the path.
FLOAT conversion will be done on the host side (or within the path).
