6.6-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit ffcd19e9f4cca0c8f9e23e88f968711acefbb37b ]
Follow the pattern of other drivers and use aligned_s64 for the timestamp. This will ensure the struct itself it also 8-byte aligned.
While touching this, convert struct mpr_chan to an anonymous struct to consolidate the code a bit to make it easier for future readers.
