From: Ben Dooks <ben.dooks@xxxxxxxxxx> [ Upstream commit 3fb787e5bad50687a65ded7f3bb805cab70dff59 ] The driver prints out 6 lines on startup, which can easily be redcued to two lines without losing any information. Note, to make the types work better, uint64_t has been replaced with ULL to make the unsigned long long match the format in the print statement.
